I think we both represent why iOS and Android are popular for different types of user. You sound like a more demanding user than me, therefore you've chosen to buy a product that suits the task. For me the iPhone does all the basic stuff like web, email, messages, social media, etc and that is good enough for me. This is why when someone tells me the iPhone is so far behind but the reality for me is not the case. Its only limited if you have the need to stretch the limits for which I don't. This doesn't really matter in my part of the world though because most people I know are on the same platform as me anywayI only agree with you on the UI consistency.
I am the more practical person wrt to fluidity. I find the ios UI feels like slow motion compared to my note3 especially scrolling. Scrolling is really bad on iPhone. Add to the horribly slow transition animation on ios is really ridiculous. I turned off animation in my note3 and window shows up much faster.
Ios can do everything for you but for me it is a major CMI. Basic stuff like automatic sound/ring profile (e.g switching to silent based on calendar entry) is non existence. So many other automation scenarios are not possible with ios. Iphone is passive like a donkey. It only does stuff when you give it a kick. My note3 does tasks for me without me lifting a finger like turning on/off sound during appropriate time or log my sms/phone activities into a calendar or warn me when my data/call limits is reached etc etc.
