I have three of your phones. I have an ASUS Zenfone 2 instead of the Droid. Are you looking to try out project Fi? That is the only reason I will keep my Nexus 6. It is too big and heavy to carry all the time. I like my S6 on the weekends for the size, camera. I am keeping my iPhone 6+ for a phone/wifi device and maybe for my son next year. I also like the ZF2 for 5.5 inch screen which fits my pocket better than the Nexus 6. Once I try Project Fi and if I do not like it due to TMO/Sprint coverage, I will sell the Nexus 6. I am keeping my line on ATT also. I also like the fingerprint ID on the S6 and iPhone 6+.
