Most of the free to air combo boxes are pretty similar interface wise. Popular at the moment is the Amiko combo box but it does not auto update channels (some of the lesser known channels can change frequency ) and not every retailer will pre load the channel list.(if you scan channels yourself on a FTA box you need to do a lot of editing afterwards) Having said that it is pretty straightforward to re tune channels and its a rare enough occurrence.
Any Tv bought in the last 5 years will have saorview built in so another option would be to buy a "Freesat" only box which has a nice interface and does auto update, the slight downside is you have to switch sources on your TV between Saorview and Freesat UK channels. Another caveat is that Freesat boxes do not carry all the free to air channels, CNN being one example.
I’ve had a free sat humax box for about 10 years, its full of features, auto updates, series link, record 2 channels at same time, pause live tv, basic but effective EPG. Why would i want to pay a subscription to sky, when 90% of the channels are available, subsciption free on Fresat. CNN was only dropped in recent months, and i don’t miss it.
The switching sources, is a “thing” alright, but i’ve got used to it.
For my other “box”, i have tried a few, but have an Nvidia Shield for 3 years, and its the best streaming box i’ve ever used, use Netflix, RTE Player, Amazon etc. and you can install whatever streaming apps you want
