I race on a carbon frame with carbon wheels and LOVE it. Handles perfectly, climbs better than I do, and corners well also. It's great for racing road races and crits, and I've done some long rides (100 miles) on it as well. I had a titanium bike at one point (that I did NOT use for racing), but it was not as nice of a ride as the carbon is for me.

Like Eden, I went from an aluminum to a carbon frame, and I swear I will never race anything else now.

FWIW - I have two carbon road bikes, a carbon TT bike, and two carbon cyclocross bikes.

I also think, however, that your experience will depend a lot on other factors as well, including geometry and fit, as Eden has pointed out.
