The former sounds formal, and depending on the context pedantic, while the latter sounds informal and is probably what most fans would say. (I have never much been a fan.)
We say "Doctors" with no "who". It sounds a bit weird to me when people refer to the character as "Doctor Who". He has been called "Doctor Who" in the show only once or twice. He was called "Doctor Who" in the 60s comics as well.This message has been edited. Last edited by: goofy,
You are of course quite right goofy. I was referring solely to how fans would say and write the title of the show. The "Doctor...who?" is often used as joke line in the show's history but the character is (almost) always referred to as simply "The Doctor".
Anyway, if you can all find it you should check out the sixth Doctor audio adventure "ish" which is all about the English Language and the quest to find the Universe's longest word. Really!

Not sure what I'd do about Doctor Who (I agree with Z on that). But, professionally if I (or anyone) is talking about plural doctors, it's always doctors Spector, or whatever. I don't consider that pedantic.
