Basically, I have a 2014 computer with 4 GB of RAM, and I’m wondering whether to use Arch, EndeavourOS, or openSUSE. I really want to try Rice and use Hyprland, but that will be my second distro. The computer is a secondary one, so it’s no big deal if it breaks.
This mainly depends on the distribution and default configuration of the desktop environment. You can make KDE Plasma use less RAM comparable to XFCE, but that’s not the case with the default setup which most people compare.
