I've enjoyed using Debian, Fedora, OpenSuse, and Ubuntu. Currently running Lubuntu. As far as desktop environments I've tried Gnome, KDE, XFCE, Mate, and LXQT. If you're new to Linux and have an older/slower machine, you may want to consider XFCE or LXQT as your DE (desktop environment) since they aren't memory hogs. I can't say I have a favorite distro. I'll probably run Lubuntu until I get a newer laptop, then I'll probably switch back to OpenSuse.
One thing to consider on those is appearance... You would be able to tweak the appearance on both, but I personally think XFCE is easier to work with. You can always do a search for how to customize the theme for any desktop environment you are running.

Woah you have tried a lot of them. I would definitely look into XFCE and LXQT.

Yeah the key to learning linux is keep researching stuff on the internet, eventually you will find all the answers.
