One of the best things about the iPhone has always been that apple designs hardware and software together. But I think iOS 8 for iPhone 6/6+ have really suffered for Apple's obsession with secrecy. It just doenst take advantage of the big screen at all. It's just iOS but bigger which I think is quite disappointing and a little lazy. Looking forward to iOS 9 though I think the big changes will all be to do with really taking advantage of the big screens - it's just a shame our 6/6+'s will have been made obsolete by then.
