For a while, I was leaning towards realCugan for anime/animation, but I recently noticed that Iris does a better job with detail preservation and detail enhancement than Cugan. And, as @kazuviking has noted, it also handles interlacing well. Cugan is great to use if the source file has no artifacts, but Iris does a better job of keeping the video sharp and preserving details while also removing artifacts. If you’re not sure where to start, you can always use Estimate as a baseline to see what the model thinks of your file, and then go from there.
This is a file that was converted from analog to digital 360p and then upscaled to 4320p. Here is the Cugan version (one pass):
And the Iris version (one pass):
