I have messed with both, and find the TC units to sound more natural, the Digitechs are nice too, but i like the smoothness of the TC sound. The newer rack mounts units from both can run off guitar or midi input, that is a big plus in the studio. For a small two voice live setup i prefer the TC harmony G
