Glad you're havin' fun, CA!
Yeah, that's the nice thing about Linux ~ seldom are you the 1st to find a snag ~ there's always sumbuddy ahead of you on the learning curve.
I haven't run Kali.
On my older, or lower powered rigs I stick with LXLE and for most noobs and recently even my new rig, I use Linux Mint. Since the Cinnamon desktop has fully come into its own I find it very capable and can tinker with it to my own liking. Where before, it was not 'configurable' enough for my personal use.
Basically, Mint just works and I'd rather use my computer to compute rather than fiddle with it all the time ~ doing that reminds me too much of Windows ~ where 50% of the time was keeping it crap-free, 40% was trying to get it to behave and the other 10% was using the damn thing.
But, as you are new to Linux and you have the basic burn-install-operate
cycle down pat, you're free to explore all the wonder of the various distros.
A decent resource with basic reviews on most distros: http://distrowatch.com/
As you've started with Kali and MInt ~ you're splashing about in the Debian-Ubuntu branch of the Linux family and there are hundreds of distros that are hanging off that branch of the Linux family tree. Stay there for familiarity's sake unless you want to really get confused ~ but the main trunks of the tree are: Debian, Arch, Red Hat and Slackware.
I guess the biggest concept for folks new to Linux is that the components that make the OS are separate entities, rather than all glommed into one amorphous mass like WIndoze.
There can be much mixing and matching of the desktop gui, window managing. and kernel in the various distros. About the only thing that hangs in the various 'families' is the repositories to load new programs and updates into the distros. That essentially, is what makes a distro a member of any major branch.
If down the road you find a distro that is to your liking but it has too many things loaded in the standard offering, or needs something else or you like with a different desktop, etc ~ guess what? YOU CAN ROLL YOUR OWN!!! Yup, there are easy to use tools that allow you to do that!
Linux puts the personal back into computing.
