I feel like the GP5000 has better grip, speed and comfort than the Gatorskin. The grip in particular feels much better.

Don't know about longevity or puncture resistance, but if this tire holds up like its reputation, I may have found my new tire . Looking forward to when the front tire wears out and I can put a GP5000 there too.

The GP5000 looks skinnier but after a couple of days at high pressure it measures almost the same in width.

I really like the fact that the sidewalls are rubber and hopefully won't "thread out" like the Gatorskins do as they age.

Don't get me wrong, the Gatorskins are a great tire (I know some don't like 'em), but the GP5000 seems more fun to ride.
