There's a big difference between trying an iphone 6 and using it for a while in real life situations. That's like saying you watched a trailer to a movie and saying it sucks. You can't judge a book by a cover friendo.
Everything you mention in your post the iphone also accomplishes. The colors on the iphone are also stunning. The camera and video are outstanding. The battery life is also great (yes the note 4 battery lasts longer) but even thought the iphone battery doesn't last as long as the note 4, that means absolutely zilch. If I need my phone to last me 9 hours without dying then that's all that matters. I can get a full 12 hour day on the iphone 6 plus so my 9 hour needs are 100% met. It doesn't matter if the note 4 can get 36 hours on a single charge, my 9 hour needs are met regardless.
So there really isn't any putting the iphone to shame involved. Like I pointed out in my prior posts. The Note 4 fingerprint reader is poor, I turned that feature off after the first week. I rarely used the S-Pen as I never really saw the functionality of it. I typed much faster on my Note 4 with my fingers than pulling out the S-Pen and trying to type. So I don't really get it. I never found my self in a realistic scenario where I needed to pull out the S-Pen and write overtop a screenshot. Not once.
Again, the fingerprint reader, the finger print integration, and the way overall way the iphone 6 plus works runs circles around the note 4. I don't care how many features the note 4 has, I rarely used them. I never needed to take screenshots by swiping my hand over the screen. They just crammed features into the note 4 for the sake of cramming in features. And most of them worked poorly.
Android devices may be about quantity (features) but Apple is 100% about quality which is why every feature they carefully add into their devices work 101 out of 100 times.
I can say one good thing about the note 4. It powers my gear VR headset and I'm happy about that.
