Cutting the cable, lets talk options and media setups

Would like to get some feedback on two things:

1. Thoughts between Sling and Vue: I've had Vue for a while and like it, but am considering whether to make the move to Sling. I like the setup thus far and appreciate that I get Fox Sports New Orleans, so no more missing Pels game. I have about a month and a half to decide between the two since I am currently on a free two month promo with Sling right now. For those that have had both, which do you prefer and why?

2. Android TV: Thinking about getting a box for my main TV in the front. Currently have my PS3 set up, but I want something with a little more flexibility. The PS3 is limited and don't have apps like Sling or anything else considered a competitor to PS Vue. The ones that I've looked at (on Amazon) all have KODI installed. Any recommendations?

Grand, I don't have Sling but I do have Vue. The one deal breaker for me with Sling is the lack of a DVR. Do you not use the DVR function much?
