I've seen a similar thesis in video form yesterday, I feel like in both cases the author forgot the fear they had before making the choice and think that sidestepping the solution to that part is no biggie.
But we're talking about people who are afraid of a black box where you type text, they need as little friction as possible.
Hindsight is 20/20
Having said all that I'm having the time of my life with cachyos, everything works great and better than it ever has in my experience running an nvidia GPU. I did do some tweaks of my own, wizh I didn't have to but it's not bad at all
How mismatched for it to cause problems or for it to be enough for people on the internet blaming it on that? In both cases I don't know tho.
I haven't visited the issue in a couple of years so hopefully that's not a thing anymore
Currently my displays work fine too, different refresh rates and bit depth (but not really, dithered 6 bit or smth).
I feel you brother, specially if you have missmatched displays, if you mention it, it's staright up your fault somehow.
I switched to mint for a few months to have the same thing I recommended my friend, I decided to switch again to something i consider bdtter for me.
There's nothing wrong with mint, at most you're missing a thing or two that are part of other base distros that you can add on your own, it's preference, that's all
Technically there can be some performance gains on a different distro but then you have to do tinkering and stuff. If I had to keep maining mint I wouldn't mind at all (and some things are way easier and painless).
One thing: browsers have had some issues in every distro I tried other than cachyos, nothing major but a bit of frame drops here and there
