For all we knew, the Witch King & his followers could have been hiding in the shadows of Moria until the Company arrived.

Whether the contest is a physical one or a battle of wills or both, the point is that the Balrog, in origin one of the Ainur like Sauron himself, is in a class above the Witch King. The contest is therefore not one between equals and the question to my mind isn't whether the Balrog can defeat the Witch King, but how long would he take to do so.
