I'd say slightly more (and, either way, that's more than enough to turn the tables against Sidious).
Given Palpatine grew substantially in power after defeating Plagueis, the fact that he underwent several rituals that "darkened the Galaxy" and that his very presence affected the Jedi's precognitive ability I'd say he should be powerful enough that a Malgus level opponent shouldn't affect the outcome of the fight.
