I'm a little biased, but I have Bantam Phoenixes, too. I raised them from chicks, so they are really docile to me. I think it's all in how you raise them, IMO.
Silkies, cochins, d'uccles, and faverolles all have pretty mellow, docile, gentle personalities.
I've also found that, if raised around people, old english game bantams and seramas are very personable, outgoing, and love socializing with people. They're also a good size for children to handle.
