We have a lot of different phones in my family and are on both VZW and TMO networks. 4 iPhone's (4, 4s, and 2 5s's), GS3, 4 GS4's, MotoX, and a BB.
I've also played with friends G2, M7, M8, and RAZR Maxx. There is nothing as snappy as the N5 on KK to date. Not even close imo. Anyone else feel this way when they pick up another mobile device?
