I got the iPhone 6, and it's definitely nice to have a normal sized phone again finally, after I abandoned Android 3 years ago. The iPhone 5s and previous phones were just so frustrating for me to text with.
The only gripe I have is that Apple didn't grow the iPhone 6 uniformly, so the height grew by about 2.5 times the width. Not a big deal, but when holding the phone with one hand which happens quite often, the phone tends to want to flip over the top of your hand, lending itself to being dropped easier. Good thing I already slapped on the ToughArmor, so the thing bounces like a rubber ball when it hits the ground.
