That's subjective though. I love Universal but don't personally rate Dudley, Popeye or Dr. Doom that highly. And a trolley?
But I agree, they have more attractions to spread the crowds out and have a variety of things to do, for everyone, so in a sense, it is more impressive than the three WDW parks you listed, and can appeal to a wide range of guests, unlike, IMO, the Disney parks now. You have a BIG selection of the guests who could visit calling MK a "kiddie park" (which is the first mistake right there; it shouldn't be). The parks have great attractions, but they need a heck of a lot more. They need to wake up and get with it. Personally, Uni has nothing to do with me saying that and they need to invest in their parks. They seem to forget "if you build it, they will come".
It really just doesn't help WDW that they haven't invested anything in DHS and Epcot for the last 8 years, minus a couple of things they more or less had to do. DHS needs more flat rides for the family (and a water ride would help immensely), Epcot needs major refurbishing for a majority of their attractions (but at least they have a couple of boat rides for everyone), and AK needs a couple of dark rides plus, IMO, about two or three more e-tickets. The lack of investment has never been more glaring.
