Not all AA is of the same quality, the effect of AA varies from game to game even if the method of AA is the same
Based on what you said, I can tell that the game doesn't provided high quality AA.If you don't care about spending some time, I would suggest that you learn to use Nvidia inspector, since it provides the best AA there is.
With Nvidia inspector you can use SSAA and SGSSAA x2 of any of those methods provides better results than the MSAA provided in most games, while also having less of a performance hit.
