Everybody knows that Blood Angels are the new hotness. They are clearly an overpowered product of GW's continuous codex creep. Haha j/k. They are, however, totally sweet and capable of making a lot of different builds that weren't possible or viable with other SM lists. You can run a list of almost all dreadnoughts, 6 predators, deepstriking land raiders, and jump packs, of course.
If you, like me, are confused about where to get started with BAs, due to the ridiculous number of options available, you should go check out Kirby's fantastic index of basic BA lists on "3++ is the new black". You won't be sorry. Click here to not be sorry
I'm kind of liking his "blood rodeo" list myself, but am most likely still going to stay the course and rock a mech 6x predator list.
