uh, I personally hate both of them. But at least fallout boy had to work to get big, Panic got signed before even playing there first gig.
Both Bands are absolutely Horrible
top axes:
Taylor GS8
Fender American Strat (w/DiMarzio pickups)
Epiphone Les Paul
It's not which one I like more, it's which one I hate less. I hate Panic! at the Disco slightly less than Fall Out Boy. They're two of my most hated bands, though.

Seriously though, delete this thread.
And if ever You come near, I will hold up high a mirror.
Lord, I could never show you anything as beautiful as You.
I thought they were the same band.
there is no fear in this heart.

How am I being or trying to be fabulous/glamorous?
