It's also like saying sharpening is better than DSR. You're just sharpening the image. DSR works with an internal higher resolution.
Metro Exodus 4k DLSS is the best example of DLSS so far and produces a much better image than RIS. Because DLSS is used properly in that game. Hardware Unboxed even admitted to this.
DLSS was a classic example of over(software)engineering, IMO. It was an interesting idea that might have turned out to have merit. But instead it turned out to not doing anything more than a standard dumb filter could do, all the while being 1000 times more complicated. It's possible to come up with very intricate ways of solving simple problems, and that's what Nvidia managed to do with DLSS. The result simply isn't that great, but meanwhile it's very impractical to implement since it requires machine learning.
I also suspect it will quietly be dropped in the next year or so, and we just won't hear anything more about it. So, I certainly wouldn't buy a 2000 series card based on DLSS.
