I guess the big question is schools, which I know nothing about. But if you stay away from the worst parts of oakland than I think almost any east bay city would be pretty good.
My wife and I live in North Oakland and we think it's very nice. It's certainly not white yuppie suburbia, but it's also not dirty run down violent west oakland. If you want something more towards the former then you probably want to look in places like the berkeley or oakland hills, rockridge, peidmont, walnut creek, etc. Basically things along Rt 24.
