Moto x Pure or Nexus 6

I've had the alcatel idol 3 for a few months. Its pretty much pure android and my first pure android phone. I love it, its awesome, but i want a bigger device and i'm done with other oems. Im not buying anything other than pure android for now on. So i'm stuck between the nexus 6 which in theory is faster than the lg g4, and the new moto x pure. I'd love to try out a 6 inch screen, im just fine with lugging it around but the moto x does have the micro sd card. so im hoping you guys can help me come to a decision.
