The Nexus 5 is still a perfect good phone. The GPE Galaxy S5 might arguably be "fresher," but for the money, the Nexus 5 is hard to beat.

Of course, you could stick with Verizon on month-to-month until the Nexus 6 (or whatever they call it) comes out, but if you're looking to jump today, the Nexus 5 is still a great device.
