2024 is the Year of Linux on the Desktop, at least for my boyfriend. He's running Windows 7 right now, so I'll be switching him to Ubuntu in a few days. Ubuntu was chosen because Proton is officially supported in Ubuntu.
I have the throw my opinion in here, I recommend Debian. Ubuntu is based off of it, as is most of the other distros people are recommending. With AMD processor and GPU, Debian has been my best OS experience to date. No bloat, recent kernel, and stable as hell. Only advantage of Ubuntu is the plethora of tutorials and guides written for it, but most of those will work with bookworm if you use Ubuntu jammy repos and guides.
I beg to differ.
The no bloat might simply turn out as an issue when they have an Nvidia Card or try to install drivers for it.
Additionally the installer is not very intuitive. (And Ubuntu has other Problems where why not just use Mint which has so many UX und GUI Features from windows, it even prompts you to install drivers using an simple GUI application)
