I haven't ever been much of an iPhone person. Outside of the "Cool Factor" of the iPhone and Siri, there's nothing that the iPhone has that the DInc4GLTE doesn't have. It's all a matter of preference.
Personally i enjoy the ability to customize android phones, the 4G speed, and there's so many choices on types of phone.
The size is very comparable, the screen is very nice, but not the Retina Display. It's sleek, easy to handle, fits in the pocket nicely, and not every DBag talks about how cool they are to have one.
I suggest you go to the VZW store and play with one and do a side by side comparison.
