I am very happy with it. I did switch from Kubuntu to Manjaro KDE, but that was not because of the GPU. The only thing that bothers me is that the fans can be noisy during some games at high load. But during everyday desktop use the fans are idle since its passive cooling capabilities are good (I have one from Powercolor, so any other brand may be different on this point). For me, the temp stays at <40°C for normal desktop use. I haven’t seen it go over 83 during gaming. You can adjust the fan curve with Corectl and even overclock it (I haven’t) if you want; but everything else just works without additional drivers/software. Now, I don’t play heavy fps games, but the games I do play are lag/stutter free. My most taxing game atm is Cities Skylines 2 and I get a solid 60fps with that and my heavily modded Minecraft runs smooth as butter. All in all, I think the card gives excellent value for money.
Not an answer to you actual question, but: I stopped using dead keys long ago because I found it irritating to have to hit space whenever I needed to break out. Instead I mapped my CapsLock to be a Compose-key which lets me make almost any symbol I ever need in a very intuitive wsy. It works everywhere (incl. Wayland).
