Depends what you're in the mood for. Extra cold if I've just been playing football, regular if it's a cold winter night, and you just want a slow drink in front of the fire.

Guinness is my long time drink of choice, but having had it all over the world from Ireland to Japan I've genuinely not had a bad one, often a badly poured one, but not a foul tasting one.

Guess my take on it is kinda like Woody Allen's take on orgasms - never had a bad one.
