which ninja is better 05-06 or 06-07?

Anyone have an opinion? I like the styling of both.
They’re both cheap at the moment as well. 636 grunt is obviously nice to have for road chores, but apparently the 07-08 model has a good mid range also.

07-08 model

05-06 model

I stunt an 05, and it has never given me any problems, I think with the newer bikes things are getting lighter and smaller and break easier, I prefer the look of the 05/06 personally:)

Do you know what the difference is between the 636 models? I’m confused by all the different abbreviations and there doesn’t seem to be any difference visually.

i would get the 05 model on looks alone even if the newer model had more power
