You should look hard at the moto X, especially if you drive allot. It is amazing. You could also go Maxx is you are on verizon and really want the battery life.
I would not trade my moto X for any of them. It gives you the same feeling as the first time you went from blackberry to android.
Google now + hands free + active notifications + always listening = game changer.
Its hard to understand it until you own it and use it for a day or two. Then there is no going back nor interest in a phone that cannot do the same functions.
