These 3 phones are very close in specs, screen resolution the same, 1080, size is close on all 3, screen size between 5.5" and 5.9". Starting price with the lowest being the Oneplus 3T, $439,then the Asus Zenfone 3 deluxe 5.7 $499, then the Mate 9 $599. Looking for opinions from people who actually own and use these 3 phones. I just wondered if the Mate 9 is actually worth the $100 & $179 price difference between the others.
