I have had all three options. I used the DVB-T aerial when our useless Freeview still offered Dolby 5.1. Quality OK but not spectacularly better than other options on 55" TV. 

I had Sky once so bought a cheap satellite box and hooked that up to the dish. It had the advantage of +1, which was handy at the time.

Then streaming arrived. I bought a box for that as well and haven't looked back since. I use Apsattv and other playlists and have more channels than I can ever watch, including the Aussie ones. Like the commercial says, NZ runs on fibre, though actually I use a WISP.
