Just got my 6S, and while I'm definitely beyond happy with the increased performance I'm encountering a whole host of new useless gimmicky features that started with either iOS 9 or 10 that I am scrambling to disable as they are simply completely unnecessary and slow down my user experience or are in the way. Features like widgets, pressing the home button twice instead of sliding to unlock, and the horrid new Messages. What the hell did they do to it? This etchasketch feature and recents/pics are just completely pointless and unnecessary. Is there any way to disable these? I'd have to say this is my main gripe with apple, forcing new useless features on us with no option to disable them. Other than that though I am very pleased with the significant boost in speed.
