I left several years ago for T-Mobile. I currently have 3 lines for $100 with unlimited data (all taxes/fees included in the flat $100), 10GB/line of hotspot tethering, plus some occasional "perks" like 25 cents off per gallon, free video rentals, etc. through the "T-Mobile Tuesdays" app. Better yet, 2 of the 3 lines are eligible for $10/off per month if you use less than 2GB of data, so the total bill goes down to $80.
I'm sure there are ways of potentially reducing that bill a bit more through other carriers, but compared to Verizon, it's a ridiculous improvement.
Edit: The third line was a recent promotion, so I think it's only available these days as a 2 lines for $100 deal, but I also believe they run that promotion (and maybe even a better one like 4 lines for $100) from time to time, and you can nab it when they do even if you are a current subscriber.
