Freshmen dorms: BSB, Speed, Deming, Mees, Scharpenberg, Blumberg
With A/C: BSB, Mees, (Scharp and Blum too, I think...)
Basic layout: Deming differs from to room, but most rooms are rectangular with two beds, a dresser, two closet armoire things, and two desks with shelves. I haven't had a problem with storage space (and I'm female), but there's generally enough room for some plastic sliding drawers from Walmart/wherever. A number of people decide to build lofts or decks for their beds, but my roommate and I kept the default bunk bed layout and it's worked wonderfully.
BSB, Mees, and Blumberg are coed by floor.
The social dynamic changes from year to year, but the Triplets (Mees, Scharp, and Blum) seem very close. However, BSB3 is also rather close this year.
The triplets are newer, and I definitely like their floor plans, but they're farther away from the academic buildings than I like. I highly prefer living in BSB where I can get to some of my classes in less than two minutes.
I don't see any major faults in any of the dorms, but it's all a matter of personal preference.
