Personally, it's not really any better than mpv filters like NIS [0] (Nvidia Image Scaling, which does not use AI but is somehow more sharp than these filters, likely because Nvidia used what they learned from AI upscaling to create a better non-AI upscaler; AMD's FidelityFX Super Resolution is also available as an mpv filter on the same page at [0]) as well as Anime4k [1] (which does use AI but only in the training phase to create the initial glsl file which then does not use AI inferencing but plain old image filters).
Combine mpv with its yt-dlp [2] and SponsorBlock support [3] and you have a competent way to upscale your own YouTube (and other types of [4]) videos.
If you really want to upscale with AI (albeit not at runtime), I've found Topaz Video AI to be the best so far, much sharper than other solutions on the market.
