Playing Devil's advocate here, but isn't a great deal of the content on Britbox available for free on various catch up's that can be seen free on a smart tv or a Firestick/Roku device? For me I guess it depends upon what original content they have to offer and whether it's stuff that's likely to interest me and of course the cost of the subscription per month. I pay £4.99 per month for the basic Netflix subscription and it's excellent, similarly oh subscribes to Amazon prime so i have access to that too and it's pretty good especially for films, not all are free of course but I refuse to pay any extra, but I've seen some great stuff. I also have Apple tv, tbh I probably wouldn't bother with it alone, but I've subscribed to Apple music for years and I was offered a package including Apple Tv and Apple games for just not much more than what I was paying for the music alone. Apple tv does some brilliant music documentaries but it is the one I tune into the least.
