For years, Motorola put out a flagship phone called the X, and for years it won positive reviews, thanks to its customizable design, clean software build and generally good value. This year, there's no X. Instead, we have two new Moto phones, the Z and Z Force. And it makes sense that Motorola chose a different naming scheme, because these are indeed very different devices from what the company has put out in years past. The design is no longer customizable, and with prices reaching $624 for the Z and $720 for the Z Force, they're not exactly what we'd call affordably priced either. Instead of being colorful and cheap, they have a modular design that allows you to snap in optional "Moto Mods" accessories, including a speaker, projector and battery pack. Another risk? Neither phone has a headphone jack. Oh, and they're exclusive to Verizon.

While we're not too pleased about those last two caveats, the Moto Mods make the Z line the best modular phones we've seen yet. The Z in particular is exceptionally thin and charges quickly, while the slightly chunkier Z Force adds longer battery life, a shatter-proof screen and a more robust 21-megapixel camera. For that reason, we gave the Z Force the higher score. But hey, if a thin phone floats your boat, you'll be happy with the Z too.
