A further note on the A7 processor: I played a good bit of Sword and Sorcery, Badland, The Walking Dead, and Liberation, and got no slowdown at all, which is what you'd expect, but still good to know. In fact, the phone didn't stutter once while I used it—not during multitasking, not while running older, non-optimized apps, just not at all—which you can't say about some other standout phones like the Moto X.
Call quality is loud and clear( Verizon), and I didn't get any dropped calls, even death-gripping it up and down while using a headset. For speakerphone, the phone itself is loud, and I was able to talk at a conversational tone from across a quiet, medium-sized office and be heard fine.
