I've been running PopOS, and it's been flawless.

I've had a very good experience with Fedora for the past few years, but I've also heard good things about Endeavor OS for an Arch based experience

Pop_OS is where it's at

Like the others say, Linux Mint. If you wanna spend a bunch more time configuring everything and solving issues then you can use other distros like Arch and Debian. For new users though, I suggest Linux Mint.

if your looking for something super beginner friendly, i would reccomend Mint (ubuntu based). if you want something slightly more work to learn, then EndevourOS (arch based, similar to manjaro), because it has Pacman and the Arch User Repository. both have good support and community, and many editions (different desktop environments preconfigured), i would recommend KDE or maybe Cinnamon (better for Mint), though it is not as big of a choice as distro (you can change DEs). KDE has a lot of awesome features out of the box, so its a great choice for beginners
