Linux

I've been using linux for over 30 years, from Linux from Scratch to Mint. Dont' pick a distro that makes you seem 1337 or anything. I must say, that for the not-so terminal-savvy user, linux Mint is a great pick, most stuff (if not all) can be done with the GUI, and the installer is a breeze.

Picking a distro is one thing, picking a desktop environment is, in my opinion, more important. With default Mint, you get Cinnamon, which is a great pick, a balance between saving resources and eye candy. You also have XFCE which is very light, but some integrations are lacking, and it's lightness shows in the basic appearance. Gnome is another beast, can almost look as slick as MacOS, but is very resource hungry. And then there's KDE. This is something your either love or hate, no inbetween.

And for every task you want to perform, you'll need to have a little selection process, since there's a lot of choices.

Steam works most of the time. I only know about NVidia cards, but with the right drivers (for which Mint has a nice tool) it works well.

As said, I've used a lot of different Linux flavours, from very hacky and compily ones to very UX oriented ones. In the end, the UX one did it for me, I just wanted something that worked. So I do recommend Mint with cinnamon.

I just moved from Windows to Linux (currently, PopOS) this year around.

You can try out beginner friendly distributions like PopOS, Linux Mint, ZorinOS which are Ubuntu-Debian based or Fedora. Like others have mentioned, applications made on Linux are expected to be cross-compatible with all distributions so your choice will mainly come down to what desktop environment you like as there are many with different feel to the user experience.

To know what works for you try these out in a VM if possible before biting the bullet so you know what all packages are present in Linux, and what all of your usecase will need to be managed through WINE/Proton compatibility layers.

You would want to avoid Ubuntu, and installing anything through Snap or PPA repositories if it ever comes up in your searches.

I think my biggest tip is to manage your expectations. What you are attempting is not the same as simply moving to a new version of Windows -- literally everything will be different. You've spent a lifetime learning how to perform all these tasks until they became second-nature, but now you plan to move to a whole new system. Thing will be in different places, the way you tweak settings or access content will be different, and it's going to be very frustrating because hey, this task should be easy. Don't expect to cram all those years of experience into re-learning a new system in a few weeks.

The good news is that there's a huge support community, and just about anything you want to do has already been asked and can be found through a quick search. Stick with it, and you'll discover that linux actually gives you quite a lot more control over what you can do with your hardware (not to mention nearly all the software is free). It won't be long before you're asking how you ever survived without many of these tools.

Install Linux, get frustrated with it, reinstall windows and live with it - repeat for over a decade until you realise the last time you installed Linux you didn't get frustrated and have been using it for the past two years.
