You know I love the GSXR. I have owned an 04 R6, an 05 GSXR 6, and now an 07 GSXR 6...and the GSXR imo is the more comfortable, and much more trqy than my old R6. I have raced 636's time and time again on my 07 and have either hung side to side or beat them, stock or with a pipe. The GSXR although not as nimble as the R6, feels more solid and has a better appeal to it that the bug (fly) look of the R6. However, choose a bike that suits you, don't buy a bike b/c someone tells you to.
