The Most Skillful Gamemode

Time for a bit of good ol' discussion.
Today, I'll cover not the best gun, not the most skilled player... but gamemodes.
What is the gamemode that requires the most skill?

Well, first off, what is skill?
Is skill being able to nuke a lot with the Skullcrusher and Python, and always having enough money to buy some armor? Or is it being able to play best in a 1v1?
Is skill based on your ability to work with your team, or your ability to be a one man army.
Maybe it's your fast reflexes. Or maybe it's something else.
Personally, I define skill as being able to play very well with almost any weapon. This means you can effectively compete with an opponent using the Skullcrusher, by wielding the M16 against them. Basically, playing effectively and for the objective using a large variety of loadouts, whether it be the most powerful assault rifle, or maybe the least effective SMG.
Some may have different interpretations of skill, some may have similar views. The definition of skill can't easily be defined in MC-War; it is your opinion on what skill is.

But what gamemode requires the most skill to play in?
First, let's go with a brief description of the gamemodes and what is supposed to happen/what actually happens in them.
Team Deathmatch (TDM)
Team Deathmatch is a gamemode where teams try to reach the kill limit the fastest. This emphasizes on pushing up to the other team's spawn, while trying to get as many kills as possible. After reaching the other team's spawn, the spawns switch, and the other team begins spawning on the other side inside. This continues until the score limit is reached. Overall, TDM is a relatively fast paced gamemode. You do not have to watch your back as often, for there are teammates often around and behind you. This makes flanking extremely effective.
In MC-War, TDM is a much slower gamemode. Maps seem to be scaled larger, so it takes much longer to traverse the map. Additionally, there are about 3x as many players (6x or 7x on server 1 or 2), which makes it much harder to push up. Because spawns do not switch, many players have given up trying to push up to the other side and instead camp around the middle of the map, picking off enemy after enemy to get a tactical nuke. However, the kill limit sometimes gets in the way, which can end the game unexpectedly before players can get their nuke.
Capture the Flag (CTF)
Capture the Flag is a much more strategic gamemode, based around capturing the other team's flag. Players focus on taking the flag of the other team. This is quite a difficult task, but it can be done. Usually, maps are smaller in CoD to allow for easier flanking and capturing. The flag is often the highest priority, with kills coming second, because it isn't easy to camp and get kills (spawns vary), you'll piss off teammates, and it isn't easy to get a good killstreak without dying.
In MC-War, maps are much larger. Commonly, the flag is either too close to spawn or too far from spawn. The single spawn point that teams have doesn't help matters, either. Also, it is extremely easy to get high numbers of kills due to the weaponry that exists in MC-War. Due to this, many players simply play CTF for kills, and usually get pissed off at people who actually try to play the game. Oh, did I mention how scavenger kind of breaks everything, and how you can reload multiple weapons at the exact same time?
Infected (INF)
Infected is more of a party gamemode, but nonetheless it is quite a fun gamemode. Players only have preset weapons to use (all players have the same loadout) against the zombies, who have knives. If an infected drops ammo from being killed (scavenger), the player must pick it up. However, the player has an equal chance to knife the infected if he's careful. Infected is a team oriented gamemode; usually working together in a team will greatly increase your chances of survival.
Due to the perks and OP weapons in MC-War, infected is pretty much an xp farm for donors. The game is extremely unbalanced and greatly favors donators. Zombies have a much harder time because they cannot lunge when knifing, and since they get knocked back by bullets. In addition, humans, of course, have OP weapons. Infected's kill system is also glitched, and zombies can utilize broken killstreaks like the EMP (it's supposed to disable electronics, not blind everyone.... it also is a killstreak that not many like...). Basically, if you have a Ray Gun, minigun, or c4 and scavenger, you win. Unless, of course, someone else has some c4.
Oh, and you can also reload both weapons at the same time.
Free For All (FFA)
Free For All is an extremely fast paced gamemode. Spawns are random, maps are small, and it's easy to get flanked. With the guns of CoD, you'll drop very fast. The kill limit is 30 and due to less players in front of you to kill, you'll easily be flanked from behind and dropped quickly. Penetration, a staple of CoD games, also makes this even easier to do. Weapons with fast reloads and good TTK times are also favored because, of course, fighting happens quickly and rather often.
In MC-War, it could be seen as pretty similar. However, the UP weapons have little to no chance against the minigun, since they take a lot longer to kill. Also, the kill limit is only 30. Killstreaks are a lot less important, with the only important one being the ammo killstreak (which is useless if you have scavenger). Guns can reload at the same time as well.
Gun Game (GUN)
Gun Game, like Infected and OITC, is also considered a party gamemode. However, it is a fast paced, pretty fun gamemode. Weapons are balanced for the most part (sidearms being an exception because... well... they're secondaries). It's a pretty fast gamemode, but it's a lot of fun. Also included is the famous Humiliation, which occurs when you knife someone and causes them to drop 1 (gun) rank.
In War, Gun Game is a hated gamemode. With the unbalances in weaponry (USP extremely weak compared to Python), you can sort of understand the reasoning behind this. However, it's the fact that you can't get KDRs as good in Gun Game that makes most "pros" hate it. Also, there's no Humiliation.
One In The Chamber (OITC)
Similar to FFA, but you only have a set number of lives. You also have just a sidearm (like a pistol, duh) and 1 bullet kills instantly. Also regarded as a party gamemode. This gamemode favors weapons like the USP and M9 (and any high firerate, fast reload, low damage sidearm in general) because bullets kill in one hit. The Executioner is known for being pretty useless because its bullets can only travel like 6-8 feet before completely disappearing. And yes, you have a knife.
War's OITC is rather disappointing in comparison. You can have any tacticals/lethals, and scavenger, of course, breaks the game as usual. However, the Executioner's bullets don't disappear after 6-8 feet, and bullets are a lot larger. As a result, the Executioner is the most used OITC weapon. Combined with molotovs, a tomahawk, and the Executioner, you can get up to 4 kills without scavenger before having to switch to your knife, assuming the molotovs kill only 1 person. And the ammo killstreak exists, which doesn't help either. Although this gamemode only affects xp (only positive), people hate it anyways because of the "BS" that happens during the game.

So which gamemode requires the most skill?
I'd definitely take infected out of this. If people didn't have OP weapons and if maps were smaller, sure. But as of right now, infected is an unbalanced pay to win gamemode.
TDM and CTF can also be eliminated. Although a few people play the objective, most play for kills and end up camping with a Skullcrusher, Python, scavenger, and super armor. Although it is arguable that one can use a lower leveled weapon, I'd like to cover the whole in general. Because honestly, not many are willing to go with the M1014 on WildWest. (who would, really?)
FFA can be easily won with a weapon that has high damage output, like the minigun or Skullcrusher. The same reasoning from above can be applied here; everyone as a whole is considered, and there's always people who will use OP weapons.
This leaves OITC and Gun Game.
They're both party gamemodes, but personally I believe Gun Game requires more skill. You can easily do well in OITC with the Executioner, DEagle, some molotovs, and scavenger.
However, in Gun Game, you are effectively forced to use crappy weapons. Those who have skill will be able to use said skill to get off to a good start in Gun Game, and even beat players with far superior guns. (for instance, player with M1014 vs player with Skullcrusher)
You cannot nuke in Gun Game with one weapon alone (and you won't be credited for those kills anyways), and scavenger is pretty useless. The fact that you cannot have tacticals, lethals, or armor and the fact that you only have 2 actual weapons (gun, knife) makes this gamemode one for the truly skilled players to excel in.

What are your thoughts on the gamemode that requires the most skill? As I said before, the opinions above are merely opinions. They are not the truth; it's how I view it.
