I'm a windows loser looking to make the plunge into Linux. I was thinking of switching my gaming PC to Linux in the near future. Before I make up my mind, I'll probably try out VMs of distros.
I've lurked a few Linux communities here and on lemmy.ml, some I'm gonna regurgitate some things I half remember in the hope of being being corrected and starting discussion about what I should be doing.
Ubuntu isn't good
Mint is good despite being based on Ubuntu. Made with former windows users in mind
Debian is good because of their packages or package manager or something. Recently sold out, but there are spinoffs that don't use proprietary software like Duvian.
Fedora seemed to get some good word but I can't remember why.
Arch and it's spinoffs require a shit ton of finagling to get right but can do a lot of cool things
There are different desktop environments like GNOME, Cinnamon, and ... others? I honestly don't know what a desktop environment is.
Wine (or the fork Proton) can run windows native games on Linux
There are snap, flat something or other, and ... other ways for installing software.
I'm sure I'm missing a lot and got some things wrong. Any help getting started is appreciated.
Edit: I ended up going with a KDE plasma spin of Fedora 36. Once I figured out how to get the nvidia drivers set up it was smooth sailing.
I think they may be referring to Systemd, which is not proprietary, but an init system very heavily criticized by some people. When Debian switched over to Systemd, there was fork made called Devuan that doesn't use systemd. But I think the init system used by a distro shouldn't be too much of a concern for a first time user. Instead they should try some popular and easy to use distro at first and then switch over to something that better suits their needs, tastes and concerns, in my opinion.
Unlikely, but they may also be referring to the fact that Stallman doesn't endorse Debian: https://www.gnu.org/distros/common-distros.en.html (though neither does he endorse a lot of other distros OP mentioned that are a lot worse in that regard)
