We are lucky, I guess..we have eight roos and they are all sweeties. But, my all-time favorites were my boy Whitey, and his son Jack Frost; Whitey was pure bred White Leghorn; his son a White Leghorn mix. Both smart, funny, friendly and full of personality; Jack Frost always befriends the quiet and shy hens, so that makes him even more valuable as he provides protection for them. Whitey lived to be 10 years old, and died defending his flock from a weasel. But we also have a Barred Cochin (dignified,quiet, smart and responsible); a black Araucauna mix roo (dead serious and very polite); another Araucauna roo (very tame and quiet, and beautiful), a Speckled Sussex roo (keeps to himself, but polite). Our other three mixed breed/ Araucauna cockerels are very shy, but polite; we haven't had them long enough to see how they'll turn out. I really kinda think that, although breed can be a factor, the roos learn from each other and also respond to a lot of friendly treatment.
