I'm sorry but it has to be the GSXR-1000 as I ride one 
the main difference i noticed was the size...bikes are getting smaller and smaller.....for the taller rider this is a problem.....apart from that it has to be personal choice...try them out if you can.
Be carefull, repect these bikes....they will all bite back if you get heavy handed with them....i'know from personal experience.
