So after having my Nexus 4 for two months and not having service because I had to wait for Sprint. I have finally activated my N4!! And the results are astonishing.
I'm on the $30 100 min, Unl text/web plan.
In the past I was paying $80 for crappy Sprint service (And that's with a 24% EMP Discount!)
Here are my results in North Miami, FL.
This is Sprint

The top two results are 4G, this is what I pay an extra $10/month for..
1.7Mbps Down .134 Mbps Up (Average from the 2 results)
And my 3G results
.651 Mbps Down .870 Mbps Up
Then we move on to the T-Mobile results...

No contest.
T-Mobile 14.00 Mbps Down 1.714 Up (Avg From 3 Results)
These tests between the 2 phones/carriers were all taken on the same server within 15 min of each other.
I haven't experienced the service much yet, but so far. This is the best financial decision I've made this year.
