I started using AMD cuz it was the "more bang for your buck" option and because of my cheapness I have always had a great experience with Linux, excluding wifi breaking every few months.
I went with AMD because I got fed up with nVidia, similarly like OP did or at least guy in the screen shot. Never looked back. Sure, AMD requires binary blob to initialize card, but it just works and zero issues since then. Upgrade hardware, just transfer drive to a new machine and voila you are ready to go.
I was on a GTX1080 for a long time. Nothing absolutely dealbreaking, but lots of small naggling issues that took lots of annoying troubleshooting to fix. Plus, abysmal DX12 performance (which is a limitation of the cards Pascal architecture as far as I know, not everyone experiences it but it's common enough).
Switched to an RX 7600XT and wow. Night and day. Zero configuration, zero weird issues, games perform fantastic at high settings (CP2077 at 1440p/High settings across the board is a pretty stable 80+ FPS, compared to 50fps at low and medium and 1080p with the old card, even on Windows). Complete gamechanger.
Same experience I had. nVidia is not a complete deal-breaker but people just don't realize how many small nagging issues owning nVidia card entails. Switching to AMD was an eye-opening event for me. Then I realized how often I got annoyed by old card.
