I like both a lot but Disneyland will always be my favorite. It's so nostalgic and while DCA is lots of fun, Disneyland for me is more enjoyable. That being said, World of Color is my favorite show out of either park, and out of all the shows and parades at WDW. Maybe get tickets to Disneyland and one park-hopper to see the shows at DCA. Then the other two just Disneyland tickets.
