I voted for Stone Temple Pilots, the main reason - their drummer, Eric Kretz, I love the way he plays (I'm not saying he's better then David Krusen or other PJ drummers) I also like the drummer Matt Cameron (my favorite Seatle Grunge band was Soundgarden - to quote Eddie Veder "can't find a better band")
I love Ten by Pearl Jam, but not into them as one of my favorite banRAB but still I am amazed by their talent. I saw a something on VH1classics (Ten revisited) and Jeff Ament was dressed like Richard Simmons with corabat boots and a rastafarian hat, I just thouhgt it was strange he wasn't wearing flannel - I thought it was a prerequisite for a Seatle band.
The band broke up a few years ago and Scott Weiland formed a super group, Velvet Revolver, with Slash, etc. They got together again and are putting an album together to be released next year.
