Well, Apache Felix, of course. ;-)
The good thing is, you don't really have to worry about it. Just program to the spec and any implementation should work fine and, if you run into issues on one, you can always switch to a different one.

Since there is no substance yet to the Java modularity JSRs, it is difficult to have much of an opinion. I think it is safe to say that no matter what comes out of the JSRs, they will not go as far as OSGi technology, so it will still have its place.
