I gotta admit, the grainless versions look sharp as shit. But they just lack texture... that certain something. I dunno.
It's only so sharp BECAUSE all the detail got stripped out. Besides texture that "detail" was in fact fuzziness around softer edges. And those filters basically pinch those fuzzy edges together into sharp contours, while removing the detail in that process. Also the noise removal removed details that weren't film grain. Its not desirable at all!
