This is getting closer to call than ever, trying them both myself I'd say stills are exceptionally comparable, but I think DLSS has the edge in motion especially thin detail like power lines, and in other titles even 2.1 doesn't quite fix disocclusion issues. Importantly, as long as this caliber or better FSR is what keeps being added to games (and lots of them), it's starting to finally deliver on being a DLSS killer imo.
I do remember major DLSS criticisms stemming from people gushing over still images, so I shouldn't need to remind everyone here that it's a best case scenario for any temporally underpinned solution. And while these comparisons serve a valuable purpose, there is unquestionably no substitute for seeing it with your own eyes - given image quality is immensely dependent on personal preference.
Well done FSR 2.1
