From SMHasher test results quality of xxhash seems higher. It has less bias / higher uniformity that CRC.
What bothers me with probability calculations, is that they always assume perfect uniformity. I've never seen any estimates how bias affects collision probability and how to modify the probability formula to account for non-perfect uniformity of a hash function.
