Many Americans (who have free access to information) have no idea that Disneyland and Walt Disney World are different places and have different attractions.
The SoCal "mentality" of WDW is that it must be better because its bigger. I can say that WDW experience is different because they are going for a week long experience as DLR has a 3 day experience. Is there more to do in WDW, yes...but that may not adjust to someone's preference. I think many of the rides are superior and the bang for the dollar is better in California...but, others will say differently for different reasons.
Its kind of like how the "public" views an airport... No two airports are the same, yet everyone attempts to navigate all airports the same way! Its not possible or feasible. Tom Bradley is not the only International Terminal at LAX...no matter what the building says!!! LOL
