I like the funnier ones like the troll face sun, the Creepers that explode into fart noises, etc. I don't like the ones that make the game unfair for other players.

I have a couple of mods and I enjoy using them; they don't affect gameplay though. One is a hi-res texture pack and the other changes all the sound effects in the game to voice overs (it's the one they put on for April Fools Day this year - I have it permanently).

I like the thirst mod.
