TXAA is terrible always so ignore it. FXAA instead of working its magic on edges like normal AA, just does it on everything, so the whole screen looks blurry, its best avoided unless you are having issues with framerate. SMAA is the same. MSAA is often the best but comes with a massive framerate hit, no blurryness and deals with jaggies the best.
Use super sampling when you can, it performs about on par with MSAA in terms of visual fidelity but often doesn't have such a huge performance hit.
