I use Apple TV and currently DirecTV now, but their platform is f$cking buggy. All I could access for most of today was A&E. I used Sling for a while, but they do not have Discovery. I ran into very few issues with Sling, it was pretty stable. We watch a bit of Netfiix also on Apple TV and it works fine. It is all my girlfriends kids watch when they are here. No issues to report with Amazon Prime on ATV either.
