From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I can't vouch for every Linux distro that claims to be user-friendly, but I've fully switched to Linux Mint a couple of months ago, and I've had no issues. The only times I've used the console are when I want to use it.
My biggest worry before fully switching was playing pirated games, or games that I bought outside of Steam, but using Lutris it has been pretty straight forward.
