I agree with 1&2.
3. I don't find either iOS or Android boring.
4. NiLs Floating Panel is the only lock screen notifications that I have used that I find better than stock iOS. Not only does it show you the notifications and allow to launch right into the app, but you also get actionable notifications, so I can delete spam email directly from my lock screen without having to go into my mail app.

5. I'm not sure about this. I stream most of my video through Hulu, Netflix, and HBO.
6. I like dropbox better because it also backups video. I use it on my iPhone too over photo stream.
7. I'm not sure I get this one. Other than syncing through iTunes, there really isn't a difference between how my iPhone and M8 interact with my Mac.
8. I sort of disagree here. I think stock android or sense android both look better than iOS, but iOS looks MUCH better than say touchwiz or LG's skin.
9. Yes, agree with you here too. iMessage and FaceTime are just so easy to use and have great quality. I FaceTime with my family all the time, there's no way I could do that with other services. My parents always call me when they try to Skype my family in South America and I always have to explain to them step by step how to log on and initiate a video call.
I still give a slight overall advantage to iOS, but Android has come a long way and on my M8 I really don't see any disadvantage in using it over my iPhone 5S, other than the camera. In fact, its been almost a month since I got my M8 and haven't really used my iPhone since, which I usually attribute to being in the "honeymoon" period, but it being a month now I may have found a new favorite phone, at least until the iPhone 6 comes out.
