Hey, gang!!

Ok, here's my setup: I currently am running my guitar through a DigiTech GNX2; Vox wah; Crybaby wah (don't ask why about two wah's...I just think it's cool and it doesn't really suck that much tone out of my guitar).

I'm thinking serious of upgrading to a Line6 POD XT Live but....I'd like to get other opinions before I take the plunge??

How much better is the Line6 POD XT Live than the DigiTech GNX2? How much better are the effects in the Line6 POD XT Live?

Any other things anybody could add is appreciated...thanks!!
