I think the main thing - well, two things really - would be 1. Numbers: the orcs are countless, and 2. The orcs know at least a bit what they are dealing with (and they would know even more if they are the initiators of this war with the purpose of getting rid of the Balrog). It seems to me that the Dwarves really had no clue what the creature was, and where he lived, and what were his habits, his abilities. The orcs, being more familiar with some of these things, would have the simple strategical advantage of thinking ahead.
