BBC is 11.88 a month and has a huge amount of new content on daily (radio as well as TV), most of it sourced in the UK, and no advertising as such
Sky is £16.50 a month and has 99% repeats across the channels that gets you...(and what is new is usually from the US), plus advertising
The fast forward through adverts isn't strictly accurate as it requires a receiver with the capability (Sky+ or HD), as opposed to being available on every box (Freeview PVR boxes can have the same capability to FF through adverts).
MAYBE..but you can't Stop your subscription to the BBC like you can VM/Sky can you now?
so it's forced upon us all even if we dont want it.
