Short and sweet.
Camera - S5
Battery - S5
How it feels in hand - S5
These three matter to me the most. Yes the M8 is pretty but it's like trying to hold onto a slippery banana and yes it is also as long as a banana. Blink Feed is a novelty as is touch wiz so who cares. The camera on the S5 is the only android camera that I have ever owned that beats my 5S. The M8 camera is crap....I know that people keep saying its not but it really is crap. Battery on the S5 hands down beats the M8, no question. Sooooo, my son gets the S5. I am waiting for the google edition. Of course though I hope that the GE is 32gb. If the next gen Moto X actually comes with a camera I may take a hard look at it but as of right now my iPhone 5S is still my daily driver. If you even have one second thought between the M8 and S5, don't. The S5 is the clear winner.
