After Nougat reaches the Google Pixel and the Samsung Galaxy 7 edge, which phone reigns supreme?

[AC Question]

Samsung makes a great phone in many ways and the Google line of phones usually makes a phone of comparable specs, but gets updates first. When both phones are using the same operating system which phone is the better phone? I know Samsung uses TouchWiz, so that will be part of the decision process. If you use a rooted Samsung device without TouchWiz share your thoughts also.
