Ugh, why can I never be done with planning?!?!?

On our 12/4 EMM day, we have Chef Mickey dinner at 7pm. Our plan was to get there 1/2 hour early and see if they could seat us, then jet over to Epcot to catch Illuminations after.
However, I realized yesterday that somewhere along in my travels, I picked up a 6pm Crystal Palace ADR.
Now I'm wondering which one we should do. We've eaten at both places so I can't use that as a deciding factor.
From a character standpoint we are seeing Minnie and Mickey at H&V on 12/6, plus we've got a breakfast at 1900 Park Fare where we'll see at least a couple of the Pooh characters.
So, it comes down to food, and timing. Why do I keep second guessing myself?!?!?
