Penn State has a stellar reputation for OB/HR, they have had excellent placements lately and publish a great deal of research. I'd say the same of Maryland, although I would place them a bit below Penn State currently although their brand has a long history of being established. For Michigan State I'd assume you are talking about the labor program. The labor program is highly ranked, but the difficulty with it is that placements from labor schools are traditionally a bit worse due to the limited number of labor schools (and the odds that you will be applying to placements in business schools).
Of course, reputation is a minor determinant, you should take a look at the research fit with specific faculty, if you like the location, and money.
