I have an easter egg/Ameraucana rooster that is just gorgeous, but not real bright (but his hens loooooove him).
I guess all these guys count as cockerels actually since they are less than a year.
But the best one is a Partridge Rock. I love Rocks generally (I have barred, buff and partridge hens) and I wanted the classic rooster look, like a Brown Leghorn or a RIR, but I refuse to tolerate a mean rooster. The partridge rock has that classic brown and red and black rooster look, like an old painting, but he is very mellow and very cool.
I have a buff laced polish rooster too, but he is just for looks. He is a great looking guy. Cant see too good because of the feathers on his head, but worth it, because he is just fabulous. If anyone gets eaten by a hawk it will be him...
I would think a Buff Orpington would be a wonderful rooster, too.
