There are a lot of different mice out there, and I cannot honestly say that you should go out and buy one rather than the other. What I can do is give a list of what I think these mice do, based on experience and heresay. Even with this information you should be a little cautious - we had two identical mice in our office on two computers, some things worked on one and not t'other! Any additions to this list would be welcome.
