Okay well it is really up to you what one you prefer,
here is a site where you can see some side by side pictures of all the body mods.
As for gear currently out there this is my opinion:
BAB: A ton of gear mostly on the side of regal looking outfits with a few skimpy ones mixed in, Medium amount of additional support from people. Has all the default gear converted. Both nude and non-nude
Exnem: Almost everything for this body is
VERY skimpy with a few exceptions. Massive amount of additional support from other people. All of the default gear has been converted. Both nude and non-nude
Fantasy Figures: (current beta release): So far almost no outfits for it. Only the default (non si) cloths have been converted (no armor yet). It does however have support for Mystic elves, Slofs Dremora, and the Si races. Both nude and non-nude.
Growlfs hot bodies: Has a huge amount of very skimpy armor (Most of it including nudity). Almost no support from other people. All of the default armor works with it (not sure about SI though I think so) Nude version only
Eshme's Bodies: I really don't know, I haven't ever used this one so I don't wanna say anything.
Hope that helps

Edit: Almost forgot, there is only one option for males and that is Robert's bodies, Not much in the way of support for this mod from other people but what there is is very high quality. All the default armor and cloths have been converted. both nude and non-nude versions
