Probably cutting the TV cord soon--advice?

So today, here’s my setup:

  • Home theater PC connected to TV
  • USB Hauppauge Dual-tuner connected to an over-the-air antenna
  • NextPVR is my comprehensive software for scheduling, recording, and watching TV
  • NextPVR uses my Schedules Direct subscription to get TV listings ($25/year)

This all works really well for me. What benefits would I get with a Plex Pass instead?
