If you have gained some Linux skills after using Ubuntu for some time, you may try switching to these distributions to explore the world of Linux distributions further.
Ubuntu is one of the best Linux distributions for beginners. It's an excellent platform for people new to Linux. It is easy to install, has tons of free resources available along with a massive list of applications available for it. https://itsfoss.com/distribution-after-ubuntu/

If you like the debian feel, you can give Devuan a try. It's Debian without systemd and what I jumped to for my desktop machines after Xubuntu.
