I have the PR Crystal, but no Frosted to compare it to.
Speaking of the PR Crystal: bending the edges a bit didn’t help to avoid pushing off the screen protector. I took a small bit of toilet paper and fold it a little bit, so it fits between the edge of the case. It seems just enough to have a little bit of room between the case and the screen protector. You barely can see it.
I don’t want to give up the PR Crystal. It feels so much more premium than the Ghost case. But it also is way heavier. I take that for granted.
