We use Verizon. Best in the Southwest from all that we tried. They recently went to a 3-tier 'unlimited' system, and which tier you are on makes a huge difference in limits before throttling, which they call 'network deprioritization.'
I replaced my Sport 22 TV with a Samsung from Costco so that I can seamlessly screen mirror from my Samsung Galaxy 9+ phone to the TV. Basically, I stream on my phone and 'mirror' this onto the TV.
The benefit to that is that limits for phone use are a lot higher than mobile hotspot limits.
Obviously the best idea is to download whatever we plan to watch while we're on WiFi but if not, having the option to mirror keeps me from getting throttled.
