I see CHAMP and ASAP rocking sigs with broken glass effects, always a great/cool touch imo. Dub did something like that but somehow managed to apply it to a wrestler to make em look like they were shattering themselves, shit was nice.
I'm guessing Photoshop comes with a shit ton more text styles? I have GIMP but I use it sparingly for just school purposes every once in a while. The styles on there are rather bland with not much variation.
Dafont makes me feel like a kid in a candy store man, it's a beautiful place. The Font ID Forum on there is worth checking out on occasion, as well.
there are others. I like to make my own fonts when I have the time.. when I don't I go to the big list o' other ppls stuffs.
To the guy using gimp. I've actually seen gimp artists that were better than a good deal of the ps artists I've known. They've all told me that it just seems to take a little bit longer to get completely used to. Sometimes gimp gives you a little lesser quality but there are ways to work around that. Just about everything you can do in photoshop you can do in gimp. Photoshop is much more idiot friendly doe. Gimp is freeware, freeware is always a little bit more work.
