All I can speak to is Coturnux, but I've found they're very easy to take care of. They don't really seek out your affection, like some chickens do, but mine are easy to handle and let me pet them when they're relaxed. Personality-wise, they can be very skittish to very tame, varying bird-to-bird and influenced by how much you handle them.
I keep mine in an aviary on the ground, so they pretty much spend all day digging holes and napping and pay me no mind unless I've got treats. If you want a really cuddly bird, Coturnix might leave you disappointed. If you want a low-maintenance bird that's fun to watch, I highly recommend them.
