I still stand by my iOS criticisms. Clunky notification systems, an overly simplified OS, behind Android with software features, and the biggest PITA is iTunes. Pricing is horrendous on the iPhone X. I had the Note 8 for a couple of months. I sold it off because I simply couldn't handle the lack of software support from my carrier for major bugs. My phone randomly rebooted and I also had some hiccups with the Note 8. Samsung is also quirky, but I notice the same quirks on the Pixel 2 as well. Quirks include: no replying to SMS or What's App messages from a lock screen, a little notification has to be tapped to log into a secure wifi rather than the web-browser opening up automatically to a sign in page, and apps aren't updated as frequently as iOS ones are.
I got the iPhone 8+ for free, but the bezels are too big and I miss the iPhone X's minimal bezels and bigger screen. I still think TouchID is better than FaceID since FaceID is really gimmicky. I am also considering the Galaxy S8+ again since it probably will drop to like $400 by the time the S9 comes out. Rather just get something that works, even if it is behind on software features and has a nice sticker price.
When I use an Apple Watch, it just synchs better and feels more premium than my Moto 360 with an iPhone or Android device. My Mac works with the iPhone really well too. I am all over the place, I know.
If Google could've taken the best of iOS (iMessage, 3D Touch, unified software + hardware process, etc) and combine it with their frequent updates, pure Android software, and offer Samsung like hardware? You're talking about a winner.
If there was a Google Play edition of the S8 or S8+, I would own that no questions asked and wouldn't even look back at iOS. If I didn't own a MacBook, I wouldn't even consider an iPhone at this time.
