I have both. Its hard for me to choose a favorite as, both pads are relatively thin and, I am not all that sensitive to differing chamois - for the most part. I guess if I had to make generalizations, then I probably have a slight preference for the Torino on longer rides, and the ION SL on short fast rides. The Torino seems a bit more absorptive, the ION SL a bit lighter and more minimalist. The Torino for events and centuries, the ION for races...I guess. In reality, I pick'em based on other attributes of the bibs and the weather.
