For class, BRS > HY but there may be a better review book than either. It may depend on how tests are written at your school so it may be best to ask around when you get there.
One series isn't better overall than the other series. Individual books are better in one series than the other.
BRS Phys and Path are good. I like HY biochem and histo. Haven't really looked much at the rest of them. I have the Goljan Rapid Review Path and really like it so far.
Hi Welcome to med school. For the boards, I would check the Step 1 forum. For class, my experience has been (and I own literally every review book known to man):
Gross Anatomy- BRS
Embryology- BRS
Biochemistry- Lippincott for biochem and High Yield for Cell Bio
Histology- Roadmap USMLE was good.
Pathology- Rapid Review by Golijan no contest.
Neuroanatomy- Neuro made ridiculously easy.
Microbiology/Immunology- Micro made ridiculously easy.
