I have an AppleTV4 and a FetchTV Mighty. Could have made do with the MIni, I never remember to record.
ON the AppleTV4 I have SBSonDemand, iView, and PLex for my local videos (I ripped all my DVDs to hard drive ages ago, lazybones me). I also pay for Netflix, at $10/month. I have no need for multiple screens or UHD, since my TV cant display that, and I live alone. I also have a SmartDNS which allows me to access the BBC, US ABC and NBC, theCW and CWSeed for all those DC Universe superhero things.
I spend most of my time on Netflix because… no ads. FetchTV is OK because its cheaper than Foxtel and gives a great spread of programs (but dont go looking for Westworld or Game of Thrones, you wont find those on Fetch). And there are no contracts. I also drop in and out of Stan once in a while. With no contracts, you can just pay for a month and see whatever you wanted at the time, then leave again until something else comes up that you like. I do the same with Netflix when I get bored with it.
