I don't think that Universal Parks have ever been considered "Thrill Ride Parks". That really is something that only Disney fans consider them. They are actually very well rounded theme parks with a little of something for EVERYONE in a family. Between both Universal parks there are only 4 large coasters. Compare that to real "Thrill Ride" parks like Cedar Point that has 15 coasters. Universal has stuff like Party in the Park with Barney, "Oh The Stories You'll Hear" in Seuss Landing, and multiple playgrounds for the toddlers. Big Boy coasters for the teens. And fine dining and a nice Spa for the adults. Because they do have a few thrill rides doesn't make them "Thrill Ride Parks".
Disney parks are very lopsided towards slow moving toddler friendly rides. And considering all the talk about Disney being "family friendly", I think they do a horrible job of actually catering to the entire family. People between the ages of 8 and young adulthood, when they start having their own toddlers, are almost entirely ignored by Disney. Sure, there is stuff they CAN do, but how much of that stuff are they actually excited to do? I believe there is a reason that most kid's favorite thing to do at WDW is the hotel pool. And teens would rather have a root canal than go to WDW. But Disney does have the "Little girls and Grandma" demo all wrapped up.
