The Legacy is a good amp, but Steve Vai won't use it without all his Rocktron and other pre-amps hooked up to it. The 5150 has a real good sound going for it but if you notice when you stop playing, even with your volume all the way down, there's a lot of background noise. Out of your choices I say go with the Line 6. It has so many things you can do with it. On top of that, if you go on their web site they tell you the settings you need to sound like any of your favorite artists from Clapton, to Vai, to Dimebag of Pantera. Plain and simple, Line 6 kicks a$$.
