Bazzite.

I found it really easy to get started with. Although I’d recommend KDE over Gnome. I tried Gnome for a few hours before changing my mind and it was just a little too different from what I was used to.

Look at the desktop environment first. KDE is like Windows. GNOME is like MacOS.

Then look at some videos about how to get your GPU working on a distro you're interested in if you have an Nvidia card. AMD GPU works out of the box.

I would recommend OpenSUSE Tumbleweed. Excellent implementation of KDE, GUI tools to do advanced things, rolling release (i.e. constantly up to date) but also thoroughly tested. Rolls back easily if something gets messed up. This gave me the least problems starting and I stuck with it for over a year. It was great.

I recently switched and have distro hopped a bit, landing on CachyOS which I feel I’ll stick with for a while (though I’m very indecisive and a small part of me wants to change over to Arch). CachyOS is based on Arch but with more ease of use stuff on top, especially for gaming (they have a gaming bundle which is just one command and you’re good to go), plus I’ve heard it’s the fastest or one of the fastest out there. Bazzite is also great (Fedora-based), which I used for a bit, but I started to get into using the command line more and found immutability to be annoying. It does mean it’s harder to fuck up though, but I don’t really care if I break my machine (you probably won’t break your machine regardless, that’s mostly sarcastic). Pop_OS! (Ubuntu-based) is also supposed to be good for gaming but I haven’t tried it. Keep in mind, if you plan on doing more than gaming and decide to use the command line for downloading, most download guides out there assume you’re using something based on Ubuntu or Debian (you’ll see a lot of “sudo apt install _____”), for better or worse. If you scroll down a bit you’ll probably find stuff for Fedora and/or Arch but not always. That doesn’t mean you can’t get the program on those distros, just that you’ll have to either know where to look or download a different way, such as from a digital storefront or manually from the website of the program you’re getting. I’m still a beginner actively trying to get better, but these are all things I would’ve liked to know when I made the switch a little while ago. Another thing to keep in mind is Linux and Nvidia don’t quite get along as well as AMD or Intel. I have an Nvidia card and both CachyOS and Bazzite had no issues, but for whatever reason Mint didn’t like to run steam games, no matter what I did. I made sure to have all the drivers downloaded and looked up a bunch of guides but I never got it running properly. Bazzite just worked straight out of the box, and CachyOS works even better for me after a little tinkering. If you have any questions, I just recently was where you are now so I might have more relevant advice, though I’m certainly no expert. But I’d be happy to help.

I started work Bazzite but didn't want to be immutable. Then I switched to Garuda. Both have been super easy.

FWIW I also switched last year and chose Linux Mint. It was smooth and easy.

I just wanted to drop in and say I use Arch btw.. lol, there multiple things to suit your use cases, Linux has a few gaming flavors.
