I got Sky Sports Now because I only really used Sky for Sports and so I can watch on any device. Kids and wife generally end up using the TV's for Play Station or movies or something while there is some sport I want to watch. It has an app so its all good.
Only issues I have found so far are during the cricket world cup there was a couple of times that the coverage/stream dropped off my phone and I had to restart the app - only happened for one of the NZ games but was annoying and happened several times during the innings. Also I have a firestick for my older Panasonic TV and it can have trouble logging on to the app at times, usually because I've been watching sport then switch to Disney or Netflix and then try and go back in to sports.
Other than those, which are minor but annoying issues I think its good. I like the on demand content, particularly highlights packages, you can watch live or from the start if you missed any of the first half for example, and the fact I can watch on any device wherever I am.
We like Sky .We watch most of the sports particularly NRL and Racing. 3 Chanels now.
We also like Discovery programs often when nothing interesting on TV.
