I have a Digitech GNX1 and Pod Xt. In my opinion the Digitech pedal offers far superior sound quality. The Pod xt is very versatile but the quality is a bit tinny and lacks punch. For example, there is nothing in the Pod that can match the Rectifier on the Digitech for power. Also, the lead sounds are not that great either. The best thing about the Pod is the accoustic sounds. I use all of my crunchy stuff through the Digitech pedal, leads through a separate Line 6 DM4 (in my opinion the best buy if you are playing metal). The reality is that you will rarely use all of the crazy effects on most pedals the distortion/overdrive sounds are most important in the decision making process, unless you play accoustic.
