IMO. Linux Mint 20 was a real disappointment. Based on ubuntu 20.04, it’s hardly surprising so many people are having problems. ubuntu 20.1 will be out soon, and Mint 20.01 should be based on that. Hopefully the new version will be better.
I tend to be the same. Jump in first, then read later.
Glad to hear you got it set up the way you like it.
I like Manjaro, it’s still my daily Linux driver. Manjaro 18 was a real effort to setup. But since version 20, IMO, Manjaro is now the easiest Linux distro to setup and maintain.
It is very slick, and always bang up to date.
If you enable the AUR option with (check for updates enabled) in the package manager. It will give you probably the most compete software catalogue of software available on any Linux distro. And, if that’s not enough you can also enable flatpak and snap.
