Well actually, if you like deb managed distro (but not the Snap drama surrounding #Ubuntu) you could take a look at #Debian itself. Their latest release is very much improved over the previous ones, because non-free software can be enabled with the click of the mouse in their default ISO image!

Btw if you liked the #LinuxMint aesthetic, but not the Ubuntu base then you could also try out their LMDE 6 (Linux Mint Debian Edition). They have Timeshift installed by default and if you change the default from Ext4 to Btrfs you have a great way to play with your system (the snapshotting I eluded to in my previous comment).

Otherwise I'd say just experiment with different distributions. In VMs or separate drives. You do you! ✌️😎
