We've kind of setted on Movies as far as Value Resorts go - mostly because the kids like the theme, and are into the Disney characters, versus the generic sports or music theme. We've stayed at all three in the past, and other than the theming, they're nearly identical.
We've enjoyed CR and PR, too - the Deluxe Resorts are better overall "expereince" and worth the extra money if you actually spend time at the resort (I find less meaningful difference between Moderate and value, personally). Since we really don't anymore - we're at the parks early and stay late - we stay at a Value Resort and apply the saving to a rental car, eliminating the bus factor and hassle altogether. I highly recommend it!
