I got some awesome speeds down in the Davie/Hollywood/Pembroke Pines area on my LG G2. I didn't look at the bands at the time though. I usually average anywhere from 20-25mbps in real time usage, but these peak speeds are awesome!
Another note, I've been a Sprint user since the beginning and have had very few calls dropped over that entire time. Data connectivity may not be great, but as a cell phone service I have been absolutely happy. I guess I just have good luck?
