We have quite a lot of material referred to Pentaceratops sternbergii, including skulls. Based on that, we know that the skulls aren't pure speculation, and this is what the skull looks like:
Not the most effective horns around, but those can still cause considerable damage. Considering the stockier build of the ceratopsian reduces its rotational inertia, it should be well-able to keep facing its opponent, rather than getting outflanked. I would give it to the ceratopsian.
