It's not just closer, but the textures look much more detailed for FSR2.1 than DLSS, and the texture settings are the same in this comparison. The texture setting was maxed out.
If you look more carefully, there is no more detail, just a sharpening filter in case of FSR. Still i consider this a positive example for FSR.

Hmm, is that so? I'm far from an expert here, but it's really obvious to me which one I think is better. The thin lines are just all smudged in the DLSS implementation, while I like how well defined the lines and edges look in the FSR2.1 implementation.

Frankly without a native image to serve as a reference, we can't really say which is doing a better job. A person can legitimately prefer one look over another, but I want to know what's doing a better job in matching the original and what performance cost I have to pay to use it.

Comparing two post-processed images against each other directly like that will invariably come down to preference, and for a lot of people that preference will probably just match their brand of choice. Unless it's done using some kind of blinding it doesn't add much value to a review or analysis.

Couldn't find the XeSS topic, so I'm posting here.

Soon we will probably see a Digital Foundry comparing all competing solutions. Death Stranding was updates and it supports everything. DLSS2, FSR1, FSR2 and now XeSS.

Videocardz.com has an article up on reviews by Tom's, pcgamer, and techpowerup on XeSS. It seems to do well enough on a lot of hardware, but, as shown in one review set, it seems to like having at least 6GB of VRAM to play with. Also, as is shown by that same slide, your hardware has to have DP4A support to see a gain. They show it on the Vega64 (which doesn't have DP4A support) and a couple of 5XXX cards (RDNA 1 didn't have DP4A support until the GPU in the 5500) where XeSS actually slows down performance. Basically, unless you have a VEGA VII or a 5500, you can't use XeSS successfully on anything before the 6000/RDNA 2 series cards. We don't have any information on the APUs, but, judging by the feature support, the 2000 and 3000 series APUs will definitely not see a gain from it (they are based on Vega 64 CUs) but it is possible that 4000 and 5000 series APUS MIGHT as they are based on VEGA VII CUs, which saw a mild shader model improvement that supported DP4A. The main concern for the Renoir and Cezanne APUs is that their limited memory bandwidth may be an issue, as it their limited compute throughput being so small in general. Also, on 8GB systems, they won't have more than 4GB of VRAM allocated, and may not even get enough in systems with more allocated depending on total memory usage.

I hope we see some comparisons of FSR2.1 vs 2.0 and see if it fixed up the main issues FSR2.0 had.
Sega's game Judgment was updates from 2.0 to 2.1, and also included XeSS.
Good opportunity to compare.

EDIT:
  • Addition of FSR2.1 Native quality.
    *Native works only when it has the same drawing resolution, adopting only the FSR2.1 Anti-aliasing effect .
It looks like AMD is finally releasing its NVIDIA DLAA alternative, an antialiasing technology powered by machine learning but rendered at native resolutions. This means higher image quality but no performance benefits from resolution upscaling.
