Paramount

Stan

Curious which one is the best?

For me it's Stan sports you get 4K plenty of panel shows not that many ads the app is easy to use. Only bad thing with them is the price for stan sports 

Depends on the content and what you're after I suppose.

I'd probably put Paramount bottom of the list at the moment though, for both functionality and content (despite having Socceroos/Matildas/APL).

and the issue is how many more options.....
This drives me nuts tbh.
Feck this tech world and companies buying out one then another or that league then the other.
Trouble is it can change within a year all over the place.

Right royal PIA.

OS is the best imo, your not going to have any being the best of the best but they do a pretty good overall package and importantly reliable.

The ads do my head in and it's not in 4K 

I don't take notice of the ads tbh and 4k no matter as well.
Small world probs to me.
My TV picture looks fine - once its refreshed all is good, I seriously dont have a issue.
