So this is my 4 days in review.
Coverage: I've only been in town. Seems fine. About the same as T-Mo and Sprint. Verizon is better thanks to small cells on the university campus and a couple more sites around town.
Call performance: Much better than T-Mobile. No call problems so far, call quality doesn't seem to be very good.
Data performance: So the definition of busy in "when the network is busy" is: if there's at least one other device using the same tower as you. I am deprioritized 24/7. Speeds are wildly inconsistent. When the network isn't being dumb the speeds are good. 40-90Mbps down and up to 12Mbps up. Pings are 110ms+ most of the time.
