Tried Plasma, didn't like it, during removal I pulled the ultimate noob move and uninstalled sddm & lightdmPlasma has actually become much more efficient these days. But for sake of ease of use, I suggest getting an ISO that has a desktop environment pre-installed so that you don't have to tinker around too much. Pretty much any light distro can extend the lifespan of your old laptops so to say. These days KDE and XFCE both use ~500MB of RAM only.
Didn't occur to me till I restarted. Traced my steps back and got lightdm back.
Pop OS felt slower than Mint xfce. Haven't tried Zorin yet.
