Best Anti-Aliasing Solution?

Hey Answers, I'm looking at recommendations for a better anti-aliasing solution. I've kicked up Unity's 8x Multi Sampling anti-aliasing solution, and the stock post-processing image effects; but I still have horrible aliasing issues on the highest settings; both in the editor and on builds. This occurring from detailed models, to the simplest box mesh.

I'd really love some recommendations/solutions, as I know there are some out there~ just can't find where.
