The choice often comes down to personal preference. I prefer Kawasaki's, which is why I purchased a Ninja ZX-14. Some people prefer what they consider to be the fastest motorcycle, not realizing that in racing, the rider skills makes all the difference.
Not everyone can ride a Ninja ZX14 or Hayabusa to its full potential. 200 HP machines, like today's newer hyperbikes, are capable of exceeding 100 mph in first gear. I am certain that the majority of street riders rarely, if ever, use more than 100 horsepower on the street.
A more powerful bike will only help you if you have the skills and the cojones to take advantage of it. In my opinion, the better rider with a lesser bike will almost always beat a faster motorcycle.
