LG G3

AT&T and Sprint customers will be able to nab the G3 first, on July 11. It will cost $199.99 with a two-year contract. Off-contract, it will be $579.99 on AT&T and $600 on Sprint. Then, on July 16, T-Mobile users will be able to purchase it for the full prepaid price of $598.80. Verizon will pick it up a day later on July 17. Its on-contract price is cheaper at $99.99, but the retail price off-contract will be $599.99.

The best part of the G3, however, has to be that there simply aren't any buttons. Unlike the S5, which has a physical home button, the G3 uses onscreen keys instead. This means that the 5.5-inch, 2,560x1,440-pixel-resolution screen grabs all of your attention, and the superthin bezel enhances that experience, making the phone appear to be "all screen."

The G3's display has an eye-popping 538 pixels per inch (ppi), while the iPhone 5S stops at 326ppi. That's 65 percent more pixels than Apple's handset, by the way. But does this really matter? In short, no. You'd be hard-pressed to tell the difference between a normal full-HD display and the QHD of the G3. The only time you could really see the difference would be if you were to put a drop of water on the screen and take a close-up shot.

Plus point: The LG G3 has solid call quality and LTE data speeds, a great camera, a brilliantly sharp display, a snappy quad-core processor, and a flat UI that makes Android 4.4 look good. LG's flagship has also improved on the previous model -- the new G3 comes with a removable battery and microSD card slot, both things the G2 lacked.

Minus point: The new QHD display with its 2,560x1,440-pixel resolution is quite a power hog, so the phone will barely last you a day without a charge.
