I believe light weight, and a carefully tuned weight distribution and sensor placement are the most significant properties for making a responsive mouse.

Anyway, the reason why the high polling rate makes a difference is that the HID spec for mice had copied the PS/2 mouse protocol — which sends updates in a continuous stream, which is ill suited for USB's polling model.
If the HID protocol instead had been designed to cater for polling at the right time rather than often, then we could have had just as fast mice without any need for fancy hardware or the need for a faster CPU just to read a peripheral better.
I think it could be done (OS internals permitting) with a custom protocol (which would require drivers), or even better: a revision to the HID protocol ... but then manufacturers wouldn't have numbers to brag with to write on the box.
