There's no question that the visually-refined HTC One M8 is one fancy piece of hand candy. Luckily, its prowess isn't just chassis-deep. The 5-inch screen is bright and sharp, the 4-'ultrapixel' camera produces pleasing photos, and the phone's quad-core processing power is one of the fastest around.

Both on paper and in the wide world, the HTC One M8 more than stands up to its fiercest competitors, the Samsung Galaxy S5 and iPhone 5S. Pay close attention to the M8's expandable storage option; HTC's inclusion of this slot knocks out one Samsung's major benefits over the original HTC One.
