I've never had a 6-inch phone/phablet because I've been intimidated by both the size and price...but I'm anxious to try. Thanks for hosting this giveaway!
Camera that works on a Nexus and great battery (what makes the Nexus 6 a step down). USB Type-C and Fingerprint scanner AND NFC (I need mobile payments OnePlus). Pure Marshmallow (without TouchWiz or Sense)as soon as it's out and the chance to use Project Fi (or any carrier you could want). Metal Build quality of the premier phones. Just the performance of the device. Kudos on the Samsung AMOLED screen Huawei.
