Having owned both, it's definitely LAH.
RCT is a great 4-flipper layout that's really fun to shoot, but where it falls flat is in the code. There are only 6 modes, and two of those are identical (Dunk the Dummy and Super Dunk). The upper loop is fun to shoot multiple times, but there's literally no switch or scoring for it. I would say RCT is an ideal candidate for a P-ROC 2.0 version.
LAH is a lot of fun to play, with a bunch of varied modes that have you shooting all over the playfield. Add in the super cheesy Arnie quotes and a super cool crane toy with a standard shaker motor that runs whenever it moves.
LAH for the win!
