Opeth or Testament?

These days, I'd take Opeth over Testament. Testament's new album was pretty trash, so I (you)'d be going for the old songs, which I (you)'ve heard a million times before.

Remember that Testament's B-Sides aren't very good. Opeth's entire catalog is quality, and you don't know what they're going to play, so you can spark up that fatty and go on a ride. Testament's gonna hit you with the same old heavies that you're gonna drink beer and head bang to like you do when you're driving drunk listening to First Strike Still Deadly.

If you DO really like Opeth, then it's a no brainer. Otherwise, figure out how you wanna spend your concert experience--with face melting thrash or progressive death metal?
 
I've seen Opeth twice and enjoyed both of the shows.
I haven't seen Testament, so for me I'd go to Testament just so I can put that notch on my belt.
I guess it would also depend on who's opening for both shows too.
 
This sounds like a testament forum, which is awesome all the same. I'm all about progressive these days, but I've always been a thrasher at heart. So yeah, testament it is! Fuck yeah!
