If I had to choose, I'd choose Kaplan. Only about 1/3 of the passages were good from TBR, but like justadream said TPRH is the best (yeah, it's a little expensive {I think around $50 from Amazon}, but the passages seemed to be closer to AAMC). I used Kaplan (online version) last time I took the MCAT and got an 11 in VR so I'm a little biased.
