Depends on the camera angle is my perception, try to make the aperture a bit higher so you can see the court and ball better..
Also check if your fps is 60.0 all the time, otherwise you find it harder to move. As for me my fps can drop sometimes on my laptop so a match can be a bit harder
then with 2d courts.
gameplay wise there is no difference, maybe you have to get used to the 3d courts.. try and alter the camera in a way you are most comfertable.
