It's frequently that case that new users of Linux think there is something to be gained by "trying" (and continuously reinstalling) different Linux distributions.
The reality is that the software that makes up Linux (iirc there are 30k packages in Debian) is generally available across all of these distributions to a greater or lesser extent.
It's all the same software with relatively minor changes made to it to fit into the particular distribution.
You can use almost any desktop environment from any of these.
The underlying system software is aligning quite a bit these days as well with systemd.
Stick with a distribution.
When something goes wrong, try not to reinstall but instead figure out the problem and fix it.
Modify the system to your liking and in the process actually learn the pieces that make it up.
Document, for yourself, the things you did so that you can be confident you actually learned something that you can reproduce.
