Well from personal experience. I think the 9 is a good bike to get.
But it all boils down to what YOU want out of it.
To me the 9 just felt more tame and easier to ride, not that the 10 is hard to ride, but this just shows the 9 is a good easy bike to ride and enjoy.
After we put aftermarket headers and the rest of the full exhaust system on it, it felt like it was so much more.
Its smooth and linear on power, handles really well, nice and comfy, has plenty of power and also better down low which is good for the street than the 10.
Bad points i guess, design could be seen as a bit outdated compared to the 10. ummm thats about all i can think of.
So i think all round youll come out a winner with a 9 esp if you get the last run of them. 03 would be an awesome bike
