The supremes are more comfortable and longer lasting. Although I've never had a flat with either tire, I've never felt comfortable riding on my GP 4 Seasons without a pump and patch kit. With the supremes, I often ride without flat repair tools even on rough stuff and, honestly, I don't worry about it. These are my 4th set of 700x32 supremes (I have them on my other bikes too) and I just feel very confident with them.
I tried to go to GPs from marathon supremes but they are not ready for the roads I have, so back to supremes it has been. Had 3 GPs fail on me during one summer. There is no ride improvement from GPs that is not more than cancelled out by 'will I get there' anxiety.
