I know this is an older thread,but. ...
I used to use Michelin pilot powers on my street bikes and it was a fantastic tire. I decided to try the Dunlop q3, it was also a great tire. Things I did notice were the initial turn in seemed a lil different with the q3. The wear between the two were similar, the Dunlop seemed to be a stickier tire when riding aggressive back road however they didn't seem to give me the feedback or "talk to me" like the pilot powers did.
Anyways I don't think you can go wrong with either tire.
