I love CyanogenMod but now HIOS by TECNO

Mkmoney:
Which smartphone UI (User Interface)is best from the following;One UI, ZenUI, OxygenOS, Cyanogenmod, Stock Android, Emotion UI, Sense UI, MIUI, Touch Wiz, Vibe UI, Optimus UI, Flyme OS, MiFavor UI, Funtouch UI, MotoBlur UI, Multi Effect Smart UI, Hive UI, Color OS, One Touch Fire OS, Xperia UI, Firefox?

Although i use Samsung's oneUI but I think oneplus oxygenOS is better I have handled the one plus7pro it feels premium.

Don't get me wrong One UI is a great move by Samsung but these are the aspects where Oxygen OS beats OneUI

Bloatware: One UI comes with a lot of bloatware (both system apps and third party apps consume a lot of memory and we can't uninstall those apps). Where as Oxygen OS is clean and bloatware free.
Updates: Oneplus gives both Android version and security updates faster than Samsung. Two year older phones like Oneplus 3T also receiving Android pie update.
Design: Samsung's Android skins have always been far from the stock Android look. And One UI is no different. However, it's much more pleasant to the eyes. The overall design appears quite refined, and Samsung has made some great decisions to improve the user experience. Where as Oxygen OS looks more like stock Android.
Apart from these three both UI s are fast and snappy when it comes to daily usuage the performance will be the same.

stock Android is the best,we all know that but minus stock Android I prefer the one UI ,then the miui,the rest i would definitely use a launcher,one UI has the best implementation of the dark mode,Nokia tried it on stock Android in the Nokia 4.2 but it didn't work out for them,I especially hate emui
