Kaplan is PMBR, which is ONLY multiple choice review (called the MBE, everyone across the country takes the same exam). Most (all?) state bar exams have a state specific essay portion.
Most people take BarBri, which reviews state law, but also does MBE review. I took BarBri, and I was pretty satisfied** with the materials and most of the lectures. That being said, many, many people do both PMBR and Bri/Bri, and some do PMBR and some other lesser known program for the essay portion.
As for whether or not PMBR uses real questions, my understanding is that the vast majority of multiple choice questions used by all the prep companies are not real questions. The bar exam is an entirely different beast than the LSAT, so reputations for LSAT prep are pretty irrelevant.
**I don't find out if I passed for another month or so, so my satisfaction could change.
