Iam mostly prefer the Motorola and Iphones........

I really like my Motorola Moto X. It'* got one of the most pure versions of Android available and no AT&T crapware, just a "My AT&T" app to view my bill and update my plan. I've had the phone almost a year and it has been the most trouble-free smartphone I've ever had and hands-down the best all around phone since my original Motorola RAZR.
