Been exclusively using Sling + Netflix + Hulu on a Roku 3 + HD antenna (for local channels) for about 4 or 5 months now and we absolutely love it. I can safely say that I'm so glad I cut the cord and am never going back to traditional cable/satellite service, unless they can get their pricing under better control. I get both the Orange and Blue packages, plus the Sports package (additional ESPN channels, ESPNU, SEC network, etc), the HBO package, and the Hollywood Extra package (all the Epix channels), and I pay about $73/mo.
I am certainly not as fine-tuned as CA in terms of audio/video quality (don't have any Grammys on my mantle), but I do consider myself fine-tuned compared to the average listener/viewer. And my standards are higher than the average person as well. Sometimes, (but very rarely), there is a minor cut from traditional HD in terms of visual artifacts. That is largely due to temporary severe slowing of ISP download speeds. I typically run at around 45-50 mbps download, and that's more than sufficient for quality HD over Sling. As I'm typing, I just ran a speed-test, and am right now only hitting about 5 mbps (Uggh! - I think the windy/stormy conditions across the southeast over the past 24hrs may be causing some regional issues), but am not noticing any issues with regard to my Sling service. Another consideration should be the quality of your wireless router. I don't care how fast your connection speed is to the house, if your router can only serve it to your device at a certain speed, that's your limiting factor.
Someone earlier mentioned that the ability to only view on one device at a time is a problem. That's true - it is. In our house, it's not, as my wife and I are generally viewing together, and the kids are mostly grown. We do have a 14yo still in the house, but he doesn't have a tv in his room and won't be viewing on any other devices. When it does become a problem is when we have grandkids in the house and my wife wants to put on Disney for them. Sling's Orange package is only single-stream (single device). Their Blue package is multi-stream (multi device). The only Sling channels that aren't currently available multi-stream are Disney, FreeForm (used to be ABC Family), and the ESPN suite (ESPN 1, ESPN 2, and ESPN 3). What that means is if the grandkids are watching some Disney show, I can't go somewhere else and watch ESPN. The workaround is that I also have the free WatchESPN app on the Roku, so I can just launch that and watch whatever I want, so long as it's not blacked out regionally (if it's available in my region as a live broadcast, it most likely will be blacked out on WatchESPN).
I personally love the interface. It's easy to see what's currently live, what will be live, and what's available on-demand, which is virtually everything. Since everything is streamed, it's coming from basically an online, on-demand library of programming. Almost every channel has almost every program available for on-demand playback. That's why lack of DVR capability isn't really an issue for me. Missed the show? Who cares - on-demand it. I've never had DVR capability anyway aside from the resident capability that came with ATT Uverse, which I used to pay enormous amounts for in order to get the channels I wanted and never watched the vast majority of the crap that came with it. I'll probably eventually get a DVR anyway and see what I can do with it in combination with the Roku/Sling service.
Anything I want to watch locally, including those SEC games of the week on CBS, I tune through the HD antenna, or if the reception is poor (the local CBS transmitter is 58.43 miles from my house), I use the $6/mo CBS All Access app on the Roku, which defaults to the CBS affiliate in Chicago. So far, CBS in Chicago has yet to not broadcast the SEC game of the week. I just need a decent Fox alternative, since there is no Fox channel on Sling, the local Fox transmitter is 56.59 miles away and is also often poor. The ABC and NBC transmitters are both close enough to get a great signal. Or maybe I'll break down and get a decent attic or outdoor antenna instead of the set-top I'm using. Then I cn cut the $6/mo CBS All Access app.
I'll put in a plug to the Roku 3 also, as the remote is handy, easy to use, has voice-search and an earphone jack in case you want to watch without disturbing anyone else.
My brother tried Playstation Vue and said it was unwatchable, due primarily to the interface. He cancelled that service and is now looking into Sling TV.
