I'd say there is no comparison, really. WCC is a table service rest. that, depending on your server, might be entertaining while you eat, much like any character meal. HDDR is a dinner show that is guaranteed silly entertainment w/ dinner with singing and dancing and corny jokes.
While we liked WCC, I wouldn't go out of my way to eat there again, unless I was staying there, but I have done HDDR twice. JMO!
