Boom HTC One X wins again.

[Bouncer]

"Do you believe in love at first sight? If so, then let us introduce you to the HTC One X. The handset is currently the top pick amongst a number of Engadget editors, and many of us have adopted it as our daily driver. Yes, the Samsung Galaxy S III is excellent in its own right, but we've taken a particular liking to the sharp S-LCD 2 display, stunning build quality and superior software environment of the One X. As with any premium smartphone, you can expect a drool-worthy camera, top-tier performance, LTE connectivity and solid battery life. If you're in a position to choose any phone on any carrier, go with the One X on AT&T and never look back."
