Linux Server Distros:

• Ubuntu Server = easier but with more bullshit out of the box (eg. snaps)
• Debian Stable = a tad bit harder because it's cleaner out of the box.
• Fedora Server = clean and easy, documentation may be a bit harder to follow, less community tutorials.
• Arch & others = Just no. You don't want a rolling release for a server. You want older and thus stable, tested, software and drivers.

If you want a distro for general use:

• Linux Mint = easiest of the bunch, but it has old packages that may not offer the best environment for gaming.

• Fedora Based distros = middle ground between ubuntu based distros like Mint, and rolling release distros like Arch.

• Arch based distros = bleeding edge drivers and packages (for better or worse), best for gaming. Manjaro could work for you, as it is not fully Arch.

• Bazzite OS = It's an immutable Fedora based distro but with Arch customized to make it work like Steam OS all inside a container. It's unbreakable, easy to use, and game-ready. Has AMD & NVIDIA images ready to go.

My recommendation is to flash Ventoy on a thumbdrive load it up with all the recommended distros, and proceed to test drive the ones you think might work for you, and only time will tell which one is the best for your specific needs.
