It's a NEXUS! Gets the fastest updates (including security). Currently using the Moto X 2nd pure and love the software but the NEXUS is the standard and will continue to be.
Thank you Paul for EC05 root and now wireless tether!!!
DFroelich: I have the experimental from the OP and got it working on EC05. Make sure 4G is turned off when you turn on wireless tether. You can turn 4G back on after.
