Linux

Zorin is designed with windows users in mind. It's very polished and it helped me make the transition.

Nvidia or AMD? If Nvidia I would especially suggest pop_OS, but really, either way that distro is great.

I started of on Linux Mint, had a couple of niggles with it so I thought 'let's be a spoony and get Ubuntu.' Got on pretty well with Ubuntu but there were a few minor things about Gnome I didn't like. I'm now on Kubuntu and it's the Goldilocks zone for me. It's been about 18 months now since I abandoned Windows 7.

I’d say go with kde as you DE. Personally I like opensuse tumbleweed.

Opensuse gives a lot of „windows like“ features like control panel etc.

Mint is what I have used to introduce people to Linux and so far only good responses. I also recommend Debian and Debian derivatives.

Depends. Whatever choice you pick - go with Plasma (KDE) desktop. Most of below choices have alternative desktop flavors that offer Plasma instead of Gnome.

If your goal is to play games - something like Bazzite might work.

If your goal is to have a desktop experience with some gaming, something like NobaraOS or PopOS would work.

If your goal is only desktop experience - ubuntu will work.

If your goal is to learn and have super awesome Linux desktop - Arch Linux.

Personally I am in Arch Linux for the past decade. Tried many different ones and Arch Linux is the only one that simply "just works" for me. Not suitable for beginners.

If history repeats itself Windows 10 is not going to die until the next good Windows floods the market

please please please avoid an LTS (long term support) distro for desktop use, especially if gaming. this includes Linux mint which is based on Ubuntu LTS. the packages are painfully old and cause problems playing the latest games, particularly where they don't work out of the box with lutris/proton/wine etc. LTS is great for servers and workstations but not end users

experienced users can make any distro work including LTS but it's extra overhead for new folks

If you're a gamer, I recommend Pop!_OS. Everything works out of the box, plus extra compatibility for Nvidia cards. It took me a second to get used to the UI, but now I can't go back.

Im going to try out Nobara when they move to plasma 6 and also EndeavourOS. One of those will suit my needs for gaming.

You can always start sooner and dual boot on Linux Mint to get familiar test your usecases. I have been dual booting and haven't logged into Windows in over 6 months. Gaming is pretty good for many games on Linux.

Most of the top answers are good so I will emphasize something that others have mentioned as well, which is that one of the lovely things about Linux is that your GUI, your window manager or desktop environment (different things I know, don't @ me) is up to you.

My personal favorite is xfce, but obviously a lot of people like KDE, Cinnamon, and Mate (mah-tay). There's of course a whole world of options beyond those, when you're choosing a distribution, go to the distro's website, and look at the screenshots. If they have different versions for different desktop environments or window managers, look at all the screenshots. Try to pick one that has a look and layout that looks comfortable to you.

Also backup your home directory. And remember you can always distro hop.

If you want to just work, just install xubuntu.
