There aren't many issues honestly and troubleshooting them isn't that bad. Malware/virus isn't really an issue on Linux, your main protection and all you really need is the forethought to not run random bullshit with root privilege. Most mainstream distros have graphical package managers, too. Your best bet is to boot a live USB and play around, check ProtonDB for your favorite games, and then install directly over your windows drive. Or I mean like a virtual machine would also be cool.

I migrated my whole family to Linux Mint, my grandma even, they all love it. I don't spend much time supporting them either which is nice, Mint is just really headache-free.
