I'm having this dilemma right now too. Definitely trading in my s8 and getting the Mate 9 or P10 Plus. I was waiting for the Mate 10 but from the leaks it seems they're going with the 2:1 screen ratio now too and I'm sick of those already AND the reported pricing puts it as expensive as the Note 8 and iPhone 8. like the size, style and battery of of the Mate 9 but the P10 Plus has a better screen and slightly better camera. The Mate 9 is also cheaper BUT the main decider for me that will probably sway me to the P10 Plus is the Finger Print Sensor on the front. My phone spends much of the day on a windscreen mount so being able to wake the phone from the front is a major thing for me and since there's no Double Tap to Wake etc on either the easiest way to wake the phone is with the front mounted FPS.
