Quail will give you eggs too, granted they won't be any where near as big. My cots have been giving me an egg a day each since they started laying. I actually got mine for raising meat so I have been trying to give away all these eggs.
Quail require a lot less space, so that may be an advantage for you. Quail can be raised indoors, another advantage for some.
I guess it depends on what you mean by tame. I can pick up my quail without issue and they will eat from my hand if I offer. I don't cuddle them though, but I don't cuddle my chickens either. Some folks have very tame quail that like to sit with them and run around the house. I think it all depends on how you raise them.
