it's kolossos because he's fun to play as, even though he's a BUM in lore strength and gameplay wise now, he's still really fun to play. KOLOSSOS MAINS WILL COME BACK IN AVENGERS DOOMSDAY- no wait that already happened, alright nevermind
My second favorite is still 2011x. He's just a easy killer to master, because he is, to me, the ONLY killer in the game, where you can freely teleport.
