All these bikes are good for reliability, they would not be the most elite production bikes in the world otherwise. In the end its your decision. Test ride them all and choose what you like.
Remember its not just about times down the 1/4, and you will never ride these bikes to their full potential around a track. If u are going to be riding several times a week and anything over 1 hr at a time you will want something that u sit comfortably on. plus if are going to throw someone on the back think about their ride too.
I had a blade and have riden the GSXR, R1 and the ninja. I definately prefered the Honda. Even my mates that had the other bikes believed the blade was a better all round package.
