I agree with a lot of your entire post, but this particularly. Mainly because I feel this is where scale tips in favor of the Pixel.
When I look at the devices out this year, I ask who pushed technology forward more as part of my consideration. Without question Pixels lead in camera technology and AI/ML. Two areas of high importance in mobile technology where the rest of the field is trailing Google.
I think the iPhone is the best out of the box experience for most people. Your 12 year old daughter and your 75 year old grandmother can both turn that device on and be up and running in minutes without any real working knowledge about technology at all and have an amazing experience. It's very easy to use, for sure. But I don't really see where they pushed things forward much this year.
IMO, the Note 9 is overpowered for most people and is just overkill for the average consumer. Most people just don't need or desire a stylus with their phones. So then the S9/9+, would make more sense.
