Best app to root a Samsung Galaxy 6

[AC Question]

I am trying to pull the contacts from my Samsung Galaxy 6 which has been damaged and the screen is all black; bought Dr. Fone Toolkit but guess what? It doesn't support the model I have and I have been told to "root" the phone. So what is the best app to root a Samsung Galaxy 6? I under that Kingoroot does not work with this particular phone.
