Moore is long, but it was my favorite source for actually learning stuff. I'm a reader, though, and like to read text instead of just lists of things to memorize, which actually doesn't seem to be the norm in med school. So, if you're like me, you'll probably like Moore. If you just want lists of of things to memorize, you'll find Moore to be a huge, inefficient waste of time.
BRS is good for the questions -- working through questions is a great (and less painful) way to solidify your anatomy knowledge. It's also good for review, but I agree that it's not great for learning the material new. But again if you're cool with just memorizing lists, BRS might be all you need.
For lab, I really liked Rohen, but I also liked to limit my time in lab. The best studying tool is probably your cadaver. Rohen isn't sufficient by itself, though, because the illustrations aren't great imo and some stuff isn't there. This is where Netter's comes in. I never looked at Grant or any of the other atlases, so I can't comment on those.
