depends on your style, my favorite right now is Eagle but I hate the G in that font tho and I really don't think anyone is really going to share what fonts they use cause you don't want to be using the same shit as someone else/vise-versa. I mean look you started this thread asking us what fonts we use only to tell us that you got a good one, well a good font does me no good if I don't know what its called. haha
crackhouse use to a favorite back in 97, now that I look at all House fonts I think there ugly. Also now if I want any type of grunge fonts I'll just use a regular font, add a layer mask to my type layer then just go to town with grunge brushes.
Hell helvetica is a great font too its really easy to read
I also never really use more then 3 on anything
