Goo Goo Dolls, since I actually like a ton of their stuff.

Second would probably be Van Halen, although that's mostly due to the debut.

No idea about the third place - I dig early Metallica, but as a whole, they've released more stuff I don't like than stuff I dig. Guns & Roses and Linkin Park each have some stuff I enjoy, but I'd never consider myself a fan.

However, this poll reminds me that I need to check me some Black Crowes. Only heard good things about them, but never bothered to check them out thoroughly.
