Lots more on there for any guitarists needs.
Amps amps amps, and some more amps.
I doubt you'd get any more out of it than your current gear, baring you don't mind taking all your gear everywhere. It definitely could replace everything but it's not social convention at gigs to turn up with no amp.
TBF, to be fair I've stopped using mine outside of recording guitar and bass for song ideas, been too busy to tweak the options etc, and as I still end up taking my rig everywhere a lot of the more useful stuff you can't turn the amp sim side off.
Ideally right now, if I could get a dual channeled input I could at least do some basic drum recording too,mans build up some tunes for the whole band to use to lay back to, refine etc.
