I've been quite happy with mine. Probably have 1000 miles so far. Lots of hills and rear tire starting to square. No punctures. I have 28mm and run them at 65psi front and 70ish rear.
Traction is excellent dry or wet as is the ride. I hear the GP5000 perform better and may try them but I have been very happy with the Gatorskins.
Only thing that is kind of weird is I notice is some threads from the sidewalls are coming loose. I've been pulling them - I suspect it is due to the lowish pressures I run.
Gatorskins get a bad rap on this site but I love em at low pressures.
