I feel like I get keys faster riding PPR for some reason? I actually like ALR more, with the exception of the night sky part of the PPR, but it just seems to take longer to get keys while riding ALR.
PPR is faster. I've gone through both rides to see why, and ALR has more ride track weaving through in at least 3 rooms. That means you spend more time riding in one room in ALR than 1 room in PPR.
