I was able to ride my friends 06 GSX-R 600.
The good: It was really nice having the gear indicator on the highway. The transmission is smooth and take effortless shifts compared to my 05 636. I love the seating position on the gixxer, as I am only 5'8" and feel very comfortable. She handled very well, and felt slim compared to the 636. The mirrors, even though I rarely use them, gave a very good view.
The bad: The GP style exhaust was really loud in lower rpms. I couldn't believe it was that loud stock, it became annoying after several minutes. The biggest issue that I had was that the bike seemed way underpowered. I can't believe the difference between the 636 and the gixxer (I thought I would never say this about any 600). It was night and day. I was bored on the gixxer after riding it for over a 1/2 hour. My friend felt the same way after driving the 636. He stated he loved the immediate power delivery of the 636, as compared to the late rush of the gixxer. Not to say the gixxer is a nice bike, but I would definaltey love to drive the 750 which would be a better balance of power and handling. In the end if you haven't ridden a 636, then you will never know what your missing.
