I have the modfactor and the timefactor. I really like both. I haven't played a G-Major, but I like them alot more than the Rocktron Xpression I had. Easier to operate too. Plus MIDI controllable. Well worth the $.
I also have the TC Nova pedals (delay, mod and reverb). These are nice pedals but they are not as full and warm as the Eventide pedals - the reverb is a cool pedal.
