Lossy video and image comparisons are pretty much worthless. Gotta use PNGs or other lossless format. In video yes zoomed in at max quality on YT and a static image shown one can see the general differences, other than that, good luck all the details get eaten away by compression and same goes for <1MB JPGs at high compression.
From still images shown so far in PNG it looks that RIS is applying too much sharpen and there is no user adjustment. So I would use lumasharpen with custom settings any time of the day because of that anyway.
They would have to look into the code and compare the algorithms, they are often very simple. Each can be tweaked in terms of strength, radius etc. comparing default settings vs default settings and saying one is sharper than the other... what is this? Really?
Each algorithm targets a different outcome. Some only want to sharpen tiny details, some want to apply high radius sharpening, some are more dumb with halos/artifacts some are smarter and have less artifacting. All of them can be tweaked in some way to alter where and how much they sharpen.
The only use for sharpening in games is to combat the poor AA implementations and their endless blur. Native with no AA is the best, period but one needs a high PPI or tolerance for the sharp "jagged/aliased" appearance.
