So far I really like Cachy. It's been great for the bit of gaming I do. I had a bit of audio grief, but installing a different kernel seemed to have fixed the issue. Overall I'm pretty damn happy with it. It was much easier than default Arch. I tried Endeavour and though it was nice, there was something about it I didn't quite like (I don't recall what). I'm off Windows entirely - between shoving their AI stuff and Ads everywhere, after decades of off and on use, Linux is my forever home.
And yeah, KDE is pretty nice and solid now.
I figure if I ever need anything Windows related, I will just load windows in a VM. Gaming wise, mostly the only games you can't play on Linux are Windows games with root kit level anti-cheats. Not sure if that is a downside...

I am running a modern PC (z790, i9-14400k, RTX 4070-Ti)
My main concern was gaming on Linux and I have been pleasantly surprised at the limited issues I have had -- only minor things.
I have recently played around with Gnome-boxes and seems to do the trick although it would be nice have GPU passthrough.
I love CachyOS and the Plasma DE and do not plan to return to Windows.
