Well one of them will have a bigger screen, the other one works. You choose.
Kidding aside, you need several Android phones in order to say that "it had that for years" or "you can do this too" ---- or you can just own one iPhone, and just in case future iPhones have a new feature or design, more likely then not you'll have it on your 5S as well (the 64bid architecture makes that possible - no need to get a new phone) spoken from a 4.5 year old experience using the 3GS from day it was released til I was able to get iPhone 5S, I was impressed how much my 3GS has changed (virtually) over the years I owned it, and on top of that, BEST BUY gave $100 for my old, scratched up, used up, dinged up iPhone 3GS when I was ready to buy the 5S. So the value of the iDevice the day you sell it is just as impressive is the day you bought it.
I stay with the iOS products specifically for the minimalist, organized, and dependent values. Design is always superb - even through the ages after new models came out, each has it's x-factor that stacks up not just against competition, but the new iPhone models. But, as I glance into the Android OS out of curiosity, it is short lived the moment you unlock the screen - Pages of Bloat, Inconsistent Menu's and Outdated OS on a NEW device - the worst is the entire OS is fighting itself to get your attention by the three "governments" within: Google, Manufacturer, Carrier - they all got their versions of the redundant bloat conflicting with the others: SmartStay wont work outside Samsung app. Smart pause only works within its player. Google now is getting pushed back by a useless S-voice. Verizon/AT&T got their idea of payment methods. Samsung got their own idea of resource management. Yet you still need antivirus $$, another keyboard software $$, and a root just to get rid of all "the voices in your phone"...
I rather have a product that the entire team has concentrated on, then a product thats part of a line up of other 15 products where the think-tank resources were rationed. I mean what other tech company invests into a sapphire production industry to make a phone? While others cant think of another spec to slap on, one company consolidates into a 64bit architecture and leaps a year forward (not to mention, nearly perfect biometric technology, house automation, in-car integration) and still keep a slim, clean design that include abilities that 4 or 5 Android put together, and if that's not enough - be able to do all that with sometimes half the specs then the competition.
