The popular Reddit posting has recently been updated. It lists the data prioritization for most popular cell phone and MVNO plans. Data prioritization comes into play when towers are congested with traffic.
I was on a Verizon QCI-9 MVNO plan and found the data unusable quite often. I changed to a Verizon MVNO on QCI-8 based on this list and my data performance improved significantly.
