I prefer getting stoned to getting drunk, mainly because I like just chilling by myself most nights.. and it's more fun getting stoned alone then drunk. (at least to me) If I'm at a place where I have to be sociable, then getting drunk is the way... or take a few shots then a few hits, that works well too.

Too drunk = headspins & puking
Too stoned = feel awesome, pass out whenever

That's my reasoning.
