Have you even read the Verge review? Particularly the Software section? Josh Topolsky writes about how limiting and frustrating iOS is becoming and how more usable Jelly Bean is comparatively.
Some highlights:
"Apple is still making users jump through hoops to perform simple tasks, like switching to a private browsing window or clearing the cache in Safari. It takes no less than six button presses and home key taps to make that happen while browsing.
Multitasking remains a black box, not representing app states and forcing what should be "always on" applications like IM clients into a constant state of shutdown warnings.... It sounds minor, but when taken as a whole and spread across multiple applications, it makes the OS feel claustrophobic, mysterious, and downright unhelpful at times.
I must mention this the fact that the weather icon continues to read 73 degrees and sunny when it is clearly possible to have icons update with at least some information (see the calendar icon) is now laughable at best, and sad at worst.
Don't get me wrong, iOS is a beautiful and well-structured mobile operating system but it's begun to show its age. It feels less useful to me today than it did a couple of years ago, especially in the face of increasingly sophisticated competition. I always have this sense now in iOS of not knowing where I am, what my status is constantly having to load things and reload them. It feels tiring.
Maybe you'll call me an Android fanboy for saying this, or maybe it's because much of my business utilizes Google apps and its communication tools, but it didn't take me very long with the iPhone 5 to start thinking about getting back to the Galaxy Nexus and Jelly Bean (Android 4.1). For what I do, I think it's a more effective, more elegant, and more powerful OS right now. What it may lack in polish and consistency, it makes up for in power and flexibility."
I encourage you to read the whole review, especially the Software section. It's about time a high-profile tech writer on a high-profile tech website is talking about iOS' shortcomings.
If you love you iPhone, kudos to you. There are others who want more out of their smartphones.
And after all that it still gets a higher rating than the s3.
I understand you have an s3 and need to justify your purchase. Just saying the reviews and benchmarks point that the iPhone 5 is better.
