It definitely is unless you happen to be 2 out of 1 million gamers that is allergic to a tiny pixel on a screen.
Using your logic, I can wipe out any aliasing in any game but smudging dirt all over my PC monitor and dropping resolution so low that everything is a washed out mess -- but eh, it removes jaggies completely!!
PS3 - Black Ops 2 is a perfect example of how TXAA is a total failure
Xbox 360 - has higher aliasing but still FAR superior IQ overall.
I quote:
"A
clear winner in Microsoft's platform, by virtue of its higher-resolution textures, superior shadow filtering, and its crisply scaled native resolution - sub-HD as it is - that looks closest of the two to the PC version's full 720p output. Sadly, the
PS3 version's image quality suffers more than it should owing to its anti-aliasing technique, which blurs over an image operating with what appears to be a dynamic framebuffer."

As I said, 99% of PC gamers would never accept AA that destroys texture sharpness/details, in effect uniqueness/crispness of PC gaming graphics over lower resolution/washed out consoles, and completely eliminates all advantages of 1440/1600P monitor gaming at the expense of wiping out aliasing through a blur filter.
People spend hundreds of hours for developing high-rez texture mods for games like Skyrim and TXAA undoes all of their hard work in 2 seconds.
Because both TXAA and FXAA are lower level AA modes compared to MSAA/SSAA that blur textures. If one cannot enable SSAA due to lack of GPU power, and SMAA is not available, the next best option is to compare MSAA/TXAA and FXAA/MLAA. In this case MSAA does a poor job of aliasing, which leaves us with FXAA vs. TXAA -- the natural comparison for this title unless you are running GTX770 SLI where you can afford SSAA. In comparing FXAA vs. TXAA IQ in this title, FXAA comes out on top in both IQ and performance; hence the comparison of performance hit of FXAA vs. TXAA.
