This is the wrong crowd for this argument, op, but I hear what you're saying. I've been playing some PS5 games and toggling between frame rates and I don't always feel like "wow this is 60 is so much better," there's definitely some nuance to it.
Interestingly in my case I think some of it has to do with how OLED TVs handle motion, there's always going to be some blur or smear no matter what due to sample and hold and I've found that 30 frames per second actually helps hide it a little bit, it's going to be blurry both ways no matter what but at a lower frame rate it's a different kind of blur, I'm blur I'm more used to from decades of low frame rate content.
A couple games I've kept at 30, and a couple I've played at 60, I think ultimately for me it depends on how much I'm moving through an environment versus how much I'm staying generally in one place and interacting with nearby things.
