You forgot Playstation Vue. It’s way better than Sling (Sling’s app is terrible), has full function cloud DVR and OnDemand access, and has access to local Comcast SportsNet channels (DirecTV Now doesn’t in Philly). I’ve been using Vue for 6 months and I did a trial of DirectTV Now and Sling. DirecTV probably has the best app (Amazon Fire), but Vue has the best content if you’re a sports fan. Sling is a distant 3rd, worst app and worst performance.
