There isn't a factual"best" one as peoples needs vary completely. That's why I say the Graphene community is toxic. They are convinced that there is only one way to do things.
Graphene is useless to me because I have no need or want for a Pixel or even a new phone. How can it be the "best" for me if I can't even use it? As it turns out there is no right answer. It might work for you but that doesn't make it the best for everyone.
