I am a Linux noobie and have only used Mint for around six months now. While I have definitely learned a lot, I don't have the time to always be doing crazy power user stuff and just want something that works out of the box.
While I love Mint, I want to try out other decently easy to use distros as well, specifically not based on Ubuntu, so no Pop OS.
Is Manjaro a possibly good distro for me to check out?
I have used it in the past for a few years. I don't think you should. Why?
The Manjaro devs are idiots. They have broken the AUR on multiple occasions.
Their packages break more often than upstream Arch since you get update bundles which they release. This isn't tested as well as it should and may lead to things breaking.
Arch is also easier to install nowadays, if you really want a rolling release distro.
If you just want something not-Ubuntu and easy to use, I tend to favor Fedora personally.
