I have been using DirectTV Now since last December. I love it. I have zero buffering and get all the sports channels. I was a early adopter so I get the $60 package for $35, plus got a free Apple TV 4. This summer, they added HBO for free.
I tried SlingTV first and it was just okay, then PS Vue. Great picture and price, but hated the interface. I will stay with DTVN and don't miss the $140 Direct TV bill. I use antenna and Tablo for local TV viewing and recording.
Same here, except I've tried nothing else. DirecTV Now is slowly adding all local channels down here in KC, which is great, and it sounds like they are close to releasing their cloud DVR, which is the only thing I miss from DirectTV. Im not sure Now is worth $60/month, but Im paying the $35 as well and it well worth that price. You can only stream on two devices at one time, but thats never been a problem for us.
