Merlin was pretty famous for having an older-skewing audience than
X Factor, so it was a very good piece of alternative scheduling by BBC One. Give the other demographics something decent to watch and you can sweep up a lot of the remaining audience.
Doctor Who is different to
Merlin in that its audience is much more evenly spread amongst the age groups, so there's more of a crossover with
X Factor at the younger end.
As far as the overall figures are concerned, and given how audiences across the board are still falling,
Doctor Who's comparing very favourably to
Merlin's final two seasons.

28/12/13 (2015-2100) - ?.??m* - Touched By the Gods: Part Two
* Failed to get into BBC One's top thirty for the week
I think I'm right in saying that the penultimate episode for each of those seasons went out the week after
X Factor finished, so BBC One had less competition
