The BBC were sending 13 bit/13 channel PCM digital streams for TV and radio (via leased GPO telephone lines) to their transmitters from 1972 onwards.
So it is very likely that anything you have ever heard on BBC FM (VHF) was distributed to the transmitter in digital.
However, yes, FM (with a good roof aerial) is my favourite despite my frequent use of Freeview radio, internet radio and iPlayer radio via AirPlay (and the TuneIn Radio Pro app).
Yet again, it's not all about the digits or 'analogue vs digital' (a dubious debate in this instance) or anything other than what the listener prefers.
I have (and regularly use) all the options including DAB (DAB on the Vita R1 in the kitchen), FM, Freeview radio, internet radio and iPlayer radio. Freeview is particularly useful for recording radio programmes on the Humax to listen to at a more convenient time.
FM still has the 'magic' that the others don't possess. This is my opinion, based on my daily experience, with my system. I also have lots of BBC Radio material purchased on BBC CDs (and ripped to iPlayer in everything from AIFF Lossless to 256K AAC VBR) so I have had the chance to compare. FM still wins - in terms of my enjoyment of the resultant sound - even if not in convenience.
Note that I am talking subjectively about my own enjoyment of/preference for FM and not measured properties, convenience, or anyone else's enjoyment.
