Well, the Balrog, as a Maia that had chosen to serve Melkor, was basically a peer of Sauron.
Actually, by the time of the Third Age Sauron had expended a great deal of his own native power in the domination of his slaves, so a Ringless Sauron could really have been substantially weaker than the Balrog.

The Nazgûl, as further diluted extensions of Sauron's spirit, could not have stood against the Balrog. Nor, do I think, could they have had many options in harming it. Their main power was in terror, though their king did have a measure of sorcery through the utter submission of his will to his master.
