I am with Tmobile (Samsung Note 2) and here are the 4G speed - pretty decent. I don't think Tmobile have LTE in memphis yet!
Around 5Mbps - download and 1Mbps - upload
I could live with those speeds. Have you been to the Olive Branch area? I am curious how the coverage is there.
I live in Midtown(38104) Memphis TN and the reception is not good here at all. Are there any carriers with decent reception in this area? I cannot use the internet in my apartment and text messages get sent or received late. I am using Boost mobile right now.
