It's Disneyland for us. Not to say we dislike DCA. We almost visit there every time we come down for a visit. DCA was actually more relaxed having less crowds, dining was not hectic, the attractions were few in which my daughter liked. So we could spend about 3 hours in DCA and then return to Disneyland where the major attractions for my daughter lived.
Growing up with Disneyland, it's rather hard for me to say that DCA is better than Disneyland. There's just too much memories and attractiveness which Disneyland pocesses.
