I distro hopped to it from Bazzite a couple of months ago, and I could not be happier.
If you try the installer, be careful when selecting multiples DE/WM as the conflicts were not listed anywhere for the installation process.
Picking a single environment and then adding the others later was what worked for me.
It’s all three! Cachy OS sets it up where it applies to both regular ram and vram. Even if just using a swap in ram, it will still be much faster than swapping to disk. Plus to the application, it looks like it has more ram/vram than there is physical ram/vram.
