We currently have an old Roku 3 box as well as an old Amazon FireTV 2 box. We love the FireTv however YouTubeTV is not available in the Amazon eco-system. We plan on using both YouTubeTV and Philo TV for our needs, both makeup for the other one’s shortcomings. My question is, is it worth buying a new Roku devivce? We don’t have a 4K tv.
