On Linux, AMD has a MAJOR advantage over Nvidia simply due to the fact that the driver is FLOSS and built into the kernel itself. This means you get full GPU support out of the box and fixes/improvements are delivered through the same update channel as the kernel.

The userland tools aren't ported to Linux however, so you don't get access to the fancy social-media-augmented gamer stuff. If you want to overclock/etc you have to rely either on a /sys filesystem interface (which wasn't stabilized when I tried it but could very well be now) or third party tools of varying quality.

As for the actual experience itself, I've owned GPUs from multiple architectures (Polaris, Raven Ridge, Vega) and I've noticed a common pattern. When the hardware is new, it's unstable. A few kernel updates later (typically over a month) they run flawlessly. To be fair a lot of the crashes/freezes I've experienced could be traced down to Mesa and LLVM. I still would give new AMD hardware time to mature though.

Performance is on par with the Windows driver package (probably because they share a lot of code). You get your money's worth. Some of the games I run on DXVK offer near-native performance.

tl;dr there's never been better a GPU driver on Linux but it's not quite ready for your grandma yet
