Follow unfollow extension bot or android based bot ?

I was wondering to ask which one is the most safer to use for follow unfollow actions is it a simple chrome extension or a android based bot like GramAddict (github).

Personally i decided to use directly chrome extension and run it on different browser profiles for each ig account.

For manual following use Multilogin, etc., but I suggest using emulators, MEMU, NOX, etc.
