I thought I'd chime in here too. I recently went from a Note 4 to an iPhone6+ and am considering buying an S6 Edge because I miss some really basic but key Android things.
I drive almost 4 hours a day, so the biggest use for my phone is as a podcast/music center on my drives. I keep my phone in landscape orientation on my dash. I hate iTunes, so use Spotify on both platforms. Here's a big deal for me right here: Spotify works in landscape mode in Android but not iOS. Seriously. Just this one simple thing has ruined my Spotify experience. I've tried to switch to iTunes because I can actually control the phone via USB in my Mazda 3, but in reality that's a world full of suddenly stopping audio - so I've switch back to Spotify and Bluetooth, which seems reliable.
Some more fun nigglies: Spofity will update it's playlists in the background on Android. On iOS I need to launch the app first. Dumb and annoying. Same with Apple's Podcast app. Won't update unless it's open. It would rule if the USB control actually worked in my car, but alas, crashes and disconnected audio has me going back to Pocket Cast and Bluetooth to enjoy podcasts. (Stitcher still sucks or maybe I'd use that).
For non-car stuff, the iPhone clearly wins. FaceTime, iMessage, AirDrop, and even the Kindle App is different and better in iOS. Simple things like tapping on the top of the screen to scroll to the top of the Facebook app is really, really cool in iOS.
Android has some wins too though: like remembering what my email address is so I don't have to retype it 1000 times like I do in iOS. That's really handy! HOLY **** - A ROW OF NUMBER ON THE KEYBOARD!! I really miss that. I can reply to incoming texts with my car's info system on Android but can't with iOS.
Battery life for me is better on the iPhone 6+ than the Note 4, FWIW.
Okay, that's all I got. YMMV!
