I've got a 3090 and I still love a bit of DLSS, it means I can smash on all those bells and whistles to full on max and gain what I would have lost if I wasn't using DLSS in doing so.
Regarding if it looks better than native, it's certainly no worse and gains fps, what's not to love.
Preach brother!
And as you know yourself, with nvidias DLDSR, you can render at a higher res. to begin with, which works extremely well with DLSS.
