Tea for me, every time I need caffeine anyway. Coffee is too deceptive. It smells great when it's brewing, and makes you think it's going to be the most wonderful tasting thing you've ever had, but when you take a swig...BITTER! Sugar and cream/milk can only mask it so much, but you're still left with the horrible nastiness of the aftertaste.

I like my tea iced and sweet, sometimes flavored too, like peach or cranberry. Mmmm~ ^^

EDIT: As for Hot Chocolate, I've always get the instant stuff that you add water to.
