Both hotels are excellent, have stayed at both , and done split stay betwenn the 2 resorts, last being last July.
PBH rooms are big and the resort is georgeous, but we have been staying at RPR for 5 years now and love it, and always plenty going on around the pool for DD to join in and make friends. PBH was extremely quiet last July, and not a lot happening around the pool, and DD was bored after the 2nd day, but would not hesitate staying again [if RPR was Full]
