Which one is better, a pure Android or an Android with a modified interface?

Everyone has to answer this question on their own, both options have their faithful supporters. Since 2016, most manufacturers rely on either pure Android or at least a discharged extension to maintain a compatibility with the applications.

This is happening mainly because Android is gradually taking over the functions previously addressed by user extensions. The fast wireless switches in the status bar an a example. While previously limited, newer Android allows each user to create their own through an application - the extension function is gradually taken over by the operating system itself.

i The trend is leaning towards pure Android and minimum manufacturer extensions.
