In my opinion, Ubuntu LTS is still a good Linux distro. The Ubuntu Yaru design is great. But with a few tips and tricks, much more can be done on an Ubuntu system. If you want to further customize the system, don't feel like using Snap and would rather set up Flatpak on Ubuntu instead, you've come to the right place.
