I like TTT the most. That's not to say I don't enjoy other gamemodes, but TTT is my goto gamemode to have a good time. It has great first-person shooter elements with CSS assets and depending on what server you go on, wacky T items that give the game a unique feel that you won't get out of any Call of Duty or Battlefield game. It's also the element of guess work and surprise that goes into it that makes it fun and competitive. Truly a fun and unique gamemode.
