You should know by now (if you don't then you should read more) that the spec sheet isn't everything. You will find many examples of how devices get smoked in the real world in side by side comparisons against other devices with 2X the specs. It isn't how many gigs or megs or pixels a device has. In most cases, its how the well the system makes use of what it has. How tightly integrated things are with each other...the hardware and the software.
Take a look at what this guy does with couple of iPhones. One is the 6+ the other is the 5S
