If you want to tinker a lot, you can always use Arch. But if you’re like me and just want your computer to work, Mint is absolutely fantastic. And I’ve run all my steam games on it without any issues. Mind you, those games were all bought for the Steam Deck, so compatibility is already sorted.
I’m number four to recommend Mint, then. Definitely a great choice for beginners. I’d also recommend starting with a virtual machine. Nuking your Windows installation without a fallback is not a good idea.
