5th Category: Personality
Both wizards are wise and experienced, but they also have a good dose of charm and humor. We know this from Gandalf, who likes to tell jokes and brings laughter to his friends. He is simply very charismatic. However, when the situation calls for it, Gandalf can also be different: he can appear threatening, loom over, raise his voice, and become intimidating.
Dumbledore is also not averse to silliness, at least in the early school years of Harry Potter. However, when the situation becomes serious, Dumbledore increasingly loses his lightheartedness and does not understand jokes anymore.
In the duel, Gandalf would throw a quip or two at his opponent. Perhaps to intimidate Dumbledore, but also to mock him and throw him off-balance with a sarcastic joke. If Dumbledore’s concentration is disrupted, Gandalf could gain a decisive advantage. Thus, the point goes to Gandalf.
