debian ang base ng ubuntu, yes, stable silaahh stable na rin ba yan ? ano pinagkaiba ng debian sa ubuntu ? yung mxlinux etc ba is feature rich na ? para ba silang mga rom variants pero ubuntu/debian based os pa din ?
parang AOSP vs OneUI (or some other manufacturer variant ng android)
yung iba kasing distro may mga prepacked apps, their own app store, driver manager, update manager, sometimes their own app repo... etc
meron din kasi mga feature na the developers think is the best implementation for them. so, it's a matter of preference
