I know this is just adding to your problem, but I wanna add to the majority and say go with Mint. It's based on Ubuntu, which in turn is based on Debian, so most anything you can do on Debian, you can do on Mint. This is handy to know whenever you see a ".deb" file.

One of the things that makes it an easier transition from windows is that it's a lot less strict about including proprietary drivers and codecs (though apparently Debian now includes a few by default). It also includes a few more GUI tools by default, like the package update manager.

I also have found Mint's Cinnamon desktop environment to be the easiest transition from a Windows environment. KDE is also a good choice in that regard and it's what I use now, but its plethora of options can be overwhelming for new users.

The distro wars can be pretty overwhelming, but I'd say pick whatever appeals most and go with it. If you get to a point where you can't do something that you want to do, you can always come back and ask for advice and maybe switch up a different OS.
