Quick release plates are great, but if you don't need the quick release ability, they add weight, they add size and they add a potential point of failure. Overall, a good QR plate should be every bit as secure as a screw mount, and potentially even more secure as they can incorporate locking mechanisms that a screw mount lacks, however, the camera still ...
Even the best quick releases do not hold so tight to whatever is attached to them as a good old screw (also on the tripods I have/had I never had to turn the camera to fix anything). This might be especially true for non-level angles. So there might be some equipment that you want to attach there, where it makes more sense to have the tight grip of a screw. ...
