LTE
Main reason I went with LTE is the external sdcard. these three phones are so close. Gnex was really in the race for me. G3 was nice but wasn't sure about the support it would have next to the LTE and the gnex. I don't regret my decision I had this puppy not even an hour and it was s-off and on my way to LTE Greatness
Gnex would be my next choice if I wasn't loving this one so much. Main reason is AOSP. Not a stable one for LTE yet but they are getting close I'm waiting for Paranoid Android to get a bit better. I flashed it and really like it. just a few issues that made me not run it as a daily yet. Mazdarider is aware of those issues.
