In the communications arena, the two are mostly compatible with one possible deal-breaker. Both employ 802.11ac for 1 Gbps Wi-Fi speeds down the road. Both also include dual-band Wi-Fi a/b/g/n, NFC, MHL, USB 3.0, Bluetooth 4.0 and 4G LTE on AT&T. That's the potential deal-breaker if your desired carrier is Sprint, T-Mobile or Verizon, all of which Samsung offers. Samsung also incorporates an infrared emitter for controlling electronics. Samsung also bonds 4G and Wi-Fi channels to create a 450-Mbps connection for faster downloads.
