I've heard from others that the GT-3 is better than the GT-5...but I've tried both and like the GT-5. I also like Digitech rack mount stuff like the 2120. I just went to see Eric Johnson and all he had was a POD and a chorus pedal. I was very impressed by that. Just play with all of them and find out what is best for you. For live stuff..I like analog pedals...nothing beats the real thing.
