I went through last football season with only PS Vue. I don't remember all the differences but I tried Hulu live, Youtube TV and Directv Now and concluded PS vue was the best bang for the buck.
Deal breakers with other services:
Channel Packages
Lack of DVR
Crap interface
Worst part of PS Vue:
Can only watch from home, to watch anything outside of your home network you have to use that channels service and log in with your PS Vue password, so you need a million apps to leave the house. (WatchESPN, BTN2GO, etc, etc,) I travel a lot so this is a pain.
Edit: The CEO of Vue resigned in November, and the new guy changed this policy.
PS Vue usually has a free 15 day trial, so if you want it for just the spring game it would be free...
