I still can't believe I feel this way but I'd have trouble going back to maybe even the Note 7 after a week with the iPhone. It's just so much better than last time I used it. Share sheets were a revolution, that solved my main complaint. Quality and smoothness and speed destroy my android phones. I still think the Note 7 is the best physical design of all time, but the build quality is top notch here. I even like the 3D Touch, better than widgets maybe (now I feel insane). I hate to gush so much I guess I was so hardcore the other way I'm still in shock.
IMO, V20 wasn't even close, but I still have my Note and Nexus 6P here. Software feels a bit rough and slow in comparison, but the freedom can't be beat. Always a trade off unfortunately. I'll be hesitant to go Note 8 rather than an anniversary iPhone next year, but I have no brand loyalty so I anxiously await the choice. I just wish the Note had more reliable software support. Samsung phones are always lousy that way.
