@OverclockedAndy I've really liked my experience with CatchyOS.
I've been primarily running Lubuntu for greater than a decade with LXDE. *edited after checking some dates - LXDE for longer than Lubuntu though.
Within the last year I installed CatchyOS on a 2010 Macbook using LXQT.
The Live USB will let you try the OS using the Plasma desktop environment prior to deciding to install.
The install is very easy and you have many options for different desktop environments allowing you to quickly try out many options. Try before you buy they say but in this case just no currency exchanged.
Good luck on your journey, there is a lot of option and choice, try not to be paralyzed by it and just try something out.
