Is Google’s material design the best?

I am wondering myself whether Google's material design standards like the 6dp distance to the left of an element and so on are the best, because if you imagine that we are all using google once a day or even more often we really get used to it's design and appearance. So with this I think if one chooses to apply the material design of Google it would create an association and would probably cause a better and trusted feeling while using the app or site. I am already interested in reading your opinion :)
