So you would favour a bigger screen and incremental speed improvements over wayyyyy less app & tab reloading. That's your call and I daresay plenty of others would agree with you. It all depends how you use your phone. For me though, the 6 Series has a fatal flaw and I would recommend that anyone with an iPhone 5 or 5C holds onto it until the 6S launches. Overall, for my requirements, the iPhone 5 was a far better phone and I wish I had saved myself £700 and stuck with mine. I would have *much* rather held onto that for a further 12 months than waste money on the half-baked 6+. A personal opinion but one I absolutely stand by. The 6S I'm sure will address this awful RAM issue and therefore it's the one to wait for. Only four more months.
We all managed with our smaller screens before the i6 came out and we could have jumped ship to Android...but didn't. The iPhone 5 is plenty good enough and is an overall better balanced phone than the i6. Sure the i6 is faster and has Apple Pay (who cares outside the US), plus it has Touch ID like the 5S and of course the bigger screen but heck, the basics like being able to go back to an app or browser tab you were in 5 minutes ago and not have it reload are worth their weight in gold to me. My old i5 still runs like a champ on iOS7.1.2 and that is in actual fact not only a better phone, but a better o/s too. Win-win, plus money in the bank towards the 6S. #
I even offered to swap my 6+ with my father for the iPhone 5 I gave him, but he said my 6+ is too big for his requirements. That's how much I prefer it.
