There are already thousands of product reviews available for this particular model, so I am not adding more to the clutter.
Still one thing that demands worth a mention is the amazing picture quality and the speed of image processing. I also happen to have a Lumia 525 so the comparison will not be too off-track. Image quality is better in Moto E. Night photography is grainy for both the models unless you have good lighting condition.
For guys who will complain about unavailability of Flash, what else do you need? There is no restriction in demand, but see what is positive in the "budget", "you" are ready to shell out and please compare peer models in same range.
