Which Model R1 is better?

I have an 02' and 04' R1 right now and I have fun with them both but I'm selling the 02' to a friend of mine and I'm thinking of getting another one. But am unsure if I should go with another 04-06 or go 07-08. What are some people's opinions? I have road a friends 07' R1 and it felt similar to my 04', but obviously had a few perks (braking, etc..)

I thought about the newer ones, but I don't like how they sound nor look.
