I have Verizon and my wife has T-Mobile. Few weeks ago we drove from Chicago to Sevierville, TN (not that far from Knoxville, TN). We were excited to put T-Mobile's data-free music streaming to test, but our excitement only lasted about 20 minutes. The moment we left Chicago area, the T-Mobile data became useless. My wife's phone was jumping between GPRS and EDGE through out the majority of the trip (I think we only saw 4G/LTE twice and only while passing thru some major cities).
For the most part T-Mobile is fine in Chicago and I have personally seen higher data speeds (up and down with lower latency vs. Verizon), but for anyone who is frequently traveling outside any major cities, I would think twice about T-Mobile.
