Right now with the limited capacity I don't think it matters much which day you go to which park. By next Easter, it's hard to say. However, I've generally been of the opinion that you should go to whichever park works best for you on each day. As long as you have a good touring strategy, the slight difference in crowds isn't all that impactful. However, my one exception to that is don't visit Epcot on weekend nights!
