I find that it affects pass quality, which is why you see more unforced bad passes on QBs throwing bullet. The 'makes it harder to catch' unlikely affects the catch ball roll, which is receiver dependent, and rather affects the pass quality of the throw.
On the other hand, it is the only way to get the ball in there before the defender arrives, so it will often make the pass easier to catch.
