Well if you want the best image quality, it should interest you, DLAA is the best AA in the business for native, and since most TAA solutions are so lacklustre, DLSS can often match or exceed native image quality because it's underpinned by DLAA, this is especially the case for 4k.
Also FWIW, Native is not the best image quality, people really need to forget that antiquated notion. Supersampling for example easily exceeds rendering at a given panels native resolution. Sure you need to downsample to that exact native pixel count, but the pixels will have better colour information for a cleaner, more detailed, and more stable image. Native rendering is a good reference point, but it's not where image quality just stops improving.
As for Steinmans amusing jab, yeah somehow I don't think Nvidia are particularly worried by AFMF, and if they are, we'd hear about it in pretty short order But hey the competition is nice and it's refreshing to see AMD's turnaround time to compete in this space improving.
