it comes down to personal preference, there might be no reason to switch when it still worksThen , I see no point in sticking to Sxos, if you install an Xci. And I am a Sxos user since the very beginning and also Atmosphere, all depends on what I want to do.
What always “made the difference” between Sxos and Atmosphere, is the availability to mount Xcis without installing anything, (for the “rest” except “maybe noob proof”, Sxos has nothing “better “ than Atmosphere and far less if we start to speak about some homebrews , overlays, sysmodules...etc..).
