Linux

Linux Mint is great, Ubuntu is ok, I'd stay away from Manjaro. The Manjaro team is known for selectively delaying updates, which can break systems sometimes.

Teams and VirtualBox both work fine on Linux, though personally I'd recommend just using teams in the browser vs downloading the app from Microsoft.

Most games work great on Linux! A really good resource for seeing if the game you want to play works is ProtonDB. There's a compatibility rating for almost every game on Steam there (even if you didn't buy the game on Steam, ratings for the Steam version should be fairly accurate). For non-steam games, WineHQ AppDB is another good resource, though I've found it can sometimes be a bit out of date when it comes to compatibility (in a good way, it'll say games are broken sometimes when they actually work fine).

For Epic, you can use the Heroic Games Launcher. It's an open-source launcher for Epic and GOG games. It'll automatically handle setting up a wine prefix for you and everything, so all you should need to do is click "install" and then "play" once it's done. Uplay is a bit more difficult, since there's no Linux-native launcher, but it's not impossible. I believe Lutris has an installer for it, you can definitely find instructions on how to do this online.

I'm not gonna lie and say that gaming on Linux is as easy as it is on Windows, especially for a beginner. These games and apps were designed for use on Windows, and if any consideration was given for Linux, it was an afterthought. However, it's completely possible for many people to never have to use Windows for gaming. It's so, sooooo much better than it was just a few years ago, and it's only going to improve from here. You might struggle a bit as a beginner, but with time you'll learn more about how all this stuff works and eventually, if a game doesn't work, in most cases you'll be able to figure out why and fix it.

Personally, I can't remember the last time I just wasn't able to get a game running on Linux at all. There was like, one instance where cutscenes didn't work, that's the worst case I've ever encountered. I mostly stick to single-player games, but still.

Clear Linux looks very performant which is interesting for gaming. And it provides choice between DEs !

I second everyone else dont use manjaro. As someone who was in a similar position to you, I started with mint just to toy around with it. Personally I'd recommended fedora, or Ubuntu (fedora over Ubuntu). I didnt stick with mint long though, eventually I just took the deep dive and installed arch as my daily driver which I wouldnt recommend unless you have time and energy to tinker with what us broken. If your uncomfortable with using Linux full time try duel booting that way you have windows as a back up system in case you bork something. If you have any questions feel free to DM me. And remember flatpak is the linux beginners best friend.

ubuntu is the most widely used distro and very simple to setup and gaming out of the box with steam is very simple. Distro end of the day doesn't matter all that much because you can change them to your hearts content, but for a beginner, you'd probably have the easiest time with an ubuntu distro.

Doesn't hurt to have virtual box windows on your linux box just so you can easily do some of that other stuff. While I have done fine with libre office for a long time there are definitely problems with formatting so having a windows VM would just solve that issue. Plus teams and w/e.

Epic games will take some serious tweaking, but not impossible.
