With carriers moving to monthly no-contract plans, the most important feature for me is that any new phone have full CDMA and GSM SIM capability. So far, the only phone with near-worldwide carrier compatibility is the iPhone 6S; nothing else comes close to it. If Apple can offer this robust CDMA/GSM capability, then why aren't the Android OEMs offering it as well? The Moto X Pure Edition is a step in the right direction, but I believe Samsung can and should offer an unlocked GS7 that covers the same broad spectrum capability as the iPhone 6S. BTW, I'm no fan of Apple.
