Faster Processor
Higher DPI Display
Thinner
Lighter
Better Camera
Larger App Store
Superior Build Quality: In terms of precision during the manufacturing process.
Those are pretty hard facts.
Faster processor... sure. I'll give you that, the megahertz myth still exists.
DPI isn't everything. Smaller displays need to be used close to your face so DPI needs to be higher.
I don't buy my phones with millimeters in mind. I think I'd rather take a phone that suits me better that is a few mm thicker than a super phone I end up hating.
Lighter. Same as above, who cares? With such minuscule differences you want even notice.
Camera. No comment. I haven't used either camera.
Apps. Again no comment. I haven't been an iOS user In a long time so my comparison is unfair.
That precision is horse ******. They don't choose from 750 glass pieces for the back. And CNC aluminum work is not Apple only. It happens daily in factories around the world.
