>>13797USE flags, all the configs, compiling everything from scratch but without it being a pain in the ass, automating nearly everything, PKGBUILDs/ebuilds, AUR, only requiring one package manager instead of 4, and needing 0-1 installations of GNOME instead of 10+ since you wont need flatpak or snap cancer\
also, customize all your shit, choose between lets say alsa and pukeaudio, or lets say kikewire if you really wanted to use that for some reason
picking between soystemdick or openrc, or whatever else you want to slap onto it
heck jewbuntu doesnt even let you pick your own WM/DE
on gentoo or parabola/arch you get a tty and install your own WM/DE, or live in a terminal if you prefer that
