I'd say battery life is most likely a draw between the two. Not a meaningful enough difference to say "this one is better".
I will definitely say the radio is better with the Motorola. That tends to be a strong point with Motorola phones.
Personally, every time I have owned a Motorola, which has only been once since I converted to smartphone a few years ago, I have always felt like I settled for a lesser option.
I definitely felt that way when I went from S2 to Electrify.
Probably the only phone I would have considered other than the S4 right now would be the HTC One.
