That’s a difficult question.

Richard Harris was really good in the first two films but he was a bit fragile looking for OOTP

I will say Richard Harris though I loved how he was especially in philosopher’s stone

(Australian btw so it will always be philosopher’s stone not sorcerer’s)

^ i agree

i'm american but philosopher's stone just sounds correct imo lol so i'm with ya

I’d say Richard Harrison. I always thought Michael Jambon didn't really fit Dumbledore’s character. Dumbledore’s personality is more calm and mysterious, and imo Michael’s portrayal of Dumbledore was a bit more on the rushed and impatient side. But I guess it did work out in later movies, when things were getting more dark. No disrespect to Michael Jambon tho. I still think he’s a fantastic actor and I have a lot of respect for him.
