iPhone 5 vs. Samsung Galaxy S4 vs. Nokia Lumia 920, the most search product review on this planet. And the result? Honestly, they are more or less the same thing. They all share on thing in common, they are too fragile to be a mobile phone like old days.
Here is a great advertisement from Nokia. I would never go back to Nokia but, that's a really nice advertisement telling the ugly truth of mobile phone fighting.
