I think that in general Digitech kit is good. I don't like their amp modeling however that is just me. I recently got rid of a GNX2 and that, for the most part sounded great.

You might want to consider spending just a little bit more and getting a model with an expression pedal as that opens up the pitch shifting and Wah effects some of my favorites !

I don't know whether Id say Boss were better than Digitech. Boss have made some really nice pedals however they have also made some real stinkers !!

Heres my current FX rig !
