Oddly, my experiences have been that my OEGB roosters have been very sweet and friendly, whereas my black Japanese rooster (who I had for eleven years until he died of old age) was mostly pretty good but got grumpy sometimes and did cause harm to me and other people a few times when hormones were raging in spring and summer. My serama rooster is a total sweetheart, and has never shown even the slightest inclination to attack me. I can pick him up and kiss him all the time, hahaha.
In general, cochins, silkies, and d'uccles are a good bet when it comes to gentle, though.
