I had the Super Puss and sold it for an El Capistan. They are pretty different tonally, but it's hard to explain unless you've tried some analog delays. The Supa Puss has pretty punchy, up-front repeats, while I feel the Capistan excels at more "ambient" washy repeats. The modulation on the Supa Puss is much more versatile, and the oscillations can get MUCH crazier (actually a little too uncontrollable on the older version I had, though they have made a newer version that is supposedly more controlled). I really dig both pedals, but ultimately I wanted more of an ambient-voiced delay and found the Capistan to do that better for my tastes. If you really want the repeats to stand out in a mix though, I think the Supa Puss might be one of the best I've tried!
