Channel selection is slightly better with Sky Max and Sky Atlantic.
Last year when we changed the out of contract price for Sky TV & Broadband was the same as the out of contract rate from Eir.
Recording with series linking doesnt work very well and it would often record every episode of the same show on every channel. if it is an often repeated show then you could rapidly end up with lots of recordings.
Recording didnt work on all channels when we had it either.
Picture quality was not great, the signal was overcompressed. Most of the time it wasnt that noticeable but in action scenes, or more importantly in fast paced field sports involving small balls it often couldnt keep up and the ball would almost disappear, or it would drop a frame or two to catch up.
Reliability wasnt great either, we regularly had to restart the box or the app as it would freeze.
I will say that Sky Q is not perfect either. I think they have turned down the picture quality intentionally on SD channels to push people to pay for HD, and our Sky Q box is probably as flaky as the Eir App on the Apple tv box. but it's a much better user experience than eir and when Limerick beat us in the hurling at least you can get to appreciate the detailed skill level they play to.
