Don't know about "professional" mice, but I for one enjoy some gaming mice. What I like about them is the high resolution, which means I don't have to move them very far. They also usually have nice feet that glide well. Higher end "regular" mice do too, but the cheaper ones usually have pretty questionable ones. Some years ago, when my trusty G9x started having some coil whine issues I got a G700s. It was the first wireless mouse I felt didn't feel wireless. Instant response, very, very smooth tracking, etc. I still use it (with its original Ni MH battery!) along with an MX Ergo wireless trackball. While the latter feels much better than I remember wireless mice used to feel, I still feel the difference when I get back on the G700s or on a corded mouse.
