B3d supports skeletal animation. 3ds doesn't.
B3d supports long texture names. 3ds doesn't.
B3d supports all of Blitz's material properties. 3ds doesn't.
Most programs that can save b3d's save the vertex normals correctly. Most programs that can save b3d's don't.
Maybe a few other things, but those are the ones that spring to mind. I now use b3d for both static and animated geometry unless I have a really good reason not to. And I can't think of a really good reason offhand.
