I gather it's purely down to preference. Some surfaces are fast & "frictionless"/low traction, some offer resistance/high traction which is better for precision, supposably. A point of the fUnc is it's double sided - one side is the frictionless type, the other with resistance. A nice idea if you dont know what you'd prefer. I use a ratpad which has been good although its worn down more than expected and am considering a fUnc, even though an awful lot of the mouspad crap is just fashion.
many "pro's" use a specific pad because theyre sponsored to do so.
fUnc 1030
Ratpadz
Everglide Giganta/Attack
Icemat (glass)
Steelpad (steel)
note some pads are known to have problems with either logitechs or ms mice, working perfectly with one but going a bit nuts with another - google your desired pad to find out which.
