What make you think cn is better global? Fixed bugs? Oh no. Not really. Some bug fixed from global, but not from cn. For example: using gestures navjgation and 3rd party launcher, notifications turn off by default, have to manually enable for every new installed apps, delay notification, too many bloated chinese apps, root using magisk and r/w system are ok, but if installing any magisk module like audio modification, you phone will got bootloop. There is only one think are good about cn version, it is 120w charging (if you have 120w stock charger).
