The Archdevil, although strong, will most likely be the first to take damage from the Archangel, which will give the Archangel a significant advantage. And if we take into account the heroes who will simply observe the battle, then the human counterattack will secure the Archangel's victory (if, of course, the condition is that the heroes do not have other abilities). Although... in a one-on-one fight, the Archdevil has a chance to use Hellfire (which means - for a while). But at the same time, the Cursed Sign, Watch, and Prayer are not used, so the Archdevil's victory is doubtful. But still, the Archangel is better!
