Yamaha R-1, Honda 1000RR, Suzuki GSX-R1000???

What's up everyone, as you can tell by my user name i am new to the game of sport bikes. My first and only bike I have owned was an old Honda 750 cruiser which was close to the weight of an A-1 abrahms tank and needless to say didn't score many looks. So I am in the market for something from this generation that can satisfy onlookers, easily customizable and comfortable to ride. I have heard from many different riders that the 600 class bikes are fun at first but slowly lose thier appeal, so I am thinking about a 1000cc class but can decide which to get. I really like the look of the R-1's, the comfort of the 1000RR, and the power of the GSX-R1000... Any help from expierenced riders for info or suggestions would be a great help!!!
