I certainly don't. However, I absolutely have noticed a reduction in my eye fatigue after a day of working. It's also very nice to move things quickly, scroll quickly, without tearing.

Need, though? No.

I'd also like it if Tidal could play without popping and hiccuping on a 12 core Xeon at idle under Big Sur (this also worked fine on Catalina, but I've not found much on this so I'm reserving my blame). I'm getting flashbacks to my 486 trying to play 320kbps MP3s...

The conversation is not about need.
