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?
If you want to divorce yourself from Ubuntu (and I think that’s a good idea myself) you can always run Linux Mint Debian Edition. Since you’re so new to Linux, I would stick with Linux Mint as your daily driver and take the time to really learn the command line, shell scripting, process control, and everything Unix-like. Get good with tools like awk, sed, grep, find, and learn about regex. Distro hopping won’t help to really learn the ins and outs.
Also take time to learn tools like iptables/nftables, ip route, IP forwarding. There’s so much you can learn without distro hopping. Once you become well versed in all things command line, then you can start searching for use case specific distro. I use Arch myself but it’s not for the beginning user.
