I think SMAA is supposed to be the best the game supports at the moment. Like all fake antialiasing strategies though it can't really deal correctly with very fine structures, and this game is full of those. All implemented AA strategies do something, but you'll see artifacts like small blobs or uneven segments in orbit lines, especially around intersections.
FXAA is supposedly the most "obvious" one because it smoothes a lot (some would say it just makes things slightly fuzzy).
As TheDynamo said, the only thing that would really work is proper supersampling which the game doesn't support natively.
