Good first distros for beginners:

• Linux Mint Debian Edition
• EndeavourOS
• Debian
• Pop! OS
• Fedora Workstation

Not Good first distros but still getting picked up by people who don't know:

• Manjaro
• Ubuntu
• Omarchy
• Zorin
• Garuda

Everyone: If you've only used one of the latter, try another distro before you believe "Desktop Linux is not ready" or "Linux is not for me".

Specifically on Steam: Which hardware you run on can affect on which distro it runs out of the box on and if you need to fiddle with drivers and firmware or not to get things running smoothly. There is also some difference between installation methods (some people swear by the flatpak version and others swear off it).

Maybe also check the health of your SSD and that your firmware/BIOS are up to date.
