Most important things in a phone? BATTERY LIFE by far.camera to logical people since you won't be carrying around another if you have a phone 80% of the time, UI , features, and display. Are you really going to notice audio with headphones? Who uses their phone speakers? It's car stereo, dock, or headphones or even tv speakers for movie viewing 90% of the time.only logical point is performance, no argument there, it can load up games 20 seconds faster, but how long can you play the games for with crap battery life? Design and so flavor is subjective, camera and battery life are not.
Not to mention no SD card slot? Completely takes away from value since all I have to do is get a 64 go SD card for $40 on amazon.also, s5 has more customizable back plates so:
Design s5
Battery s5
Display s5
Value s5
Camera s5
Audio moto x
Performance tie since battery life is just as important as speed of loading
UI is subjective so tie
Features s5 [u water proof and more camera options? S health?]
Clearly this dude is smoking something.
