Looking back at my posts in this thread, on RTX Ultra/Ultra Settings and DLSS set to “balanced” I was getting a low 60’s at a min and sometimes as high as 80’s. Cyberpunk with the same (equivalent) settings, I’m seeing the (very) rare dip into the 58-60 range (I believe I saw this once in a while in Legion, as well), but generally it’s running in the mid to high 60’s, and sometimes into the 70s so I’d guess the average is around 10 fps less than Legion at most, though one thing C2077 does I love with the DLSS set to AUTO is lower the resolution a bit during driving or maybe (I assume, I have never seen it happen, during lots of action during combat), so I maintain high 60’s and into the 70’s while driving but it still looks excellent due to the fast movements blurring/hiding any lowered resolutions I may be otherwise seeing, and then returning me to a higher resolution when the action slows back down and I get out of the vehicle (or reduce speed).
I do believe, looking at images I posted in this thread and screens I grabbed from C2077, that Cyberpunk has nicer textures (at least on equivalent Ultra settings) - the world looks a little more dense and “lived in” here, seems like. It could just be I like the art and the imagantive world building in Cyberpunk more, admittedly.
TL:DR; in practice, they feel the same to me.
