HTC One M8
The HTC One M8 is as good as last year's HTC One M7 which was considered by many to be one of the best smartphones of all time. So it should come as no surprise that its listed here amongst the best AT&T smartphones money can buy.
The new version of the HTC One comes with a premium metal design though HTC has added a microSD card slot for expanded storage. It also comes with a fantastic camera, HTC BoomSound speakers, a larger 5-inch 1080p display, and new motion gestures that work in conjunction with the device's Sense 6 software.
Like the Galaxy S5, AT&T's HTC One M8 has seen its price slashed numerous times since its launch in April and thus, consumers will need to keep an eye out for discounts this month.
