I think it depends on how you want to use it. I got a PODxt Live to hook up to my PC for easy recording, and I carry it as an emergency rig when I'm out playing, but have not used it live yet. The POD has USB, which the others don't. If you want to use the zoom with a PC to record or to edit patches etc you'll need a midi device of some sort and a cable. When I had the choice it was GT8 or PODxt, the USB connectivity was the winner really - I tweaked both of them to get the sounds I wanted. What amp will you put it through>?
No idea on the quality of it, but yeah, the reviews are good. Harmony Central link here if anyone is interested...
