It kind of depends on what you consider a thrill ride. I'm used to Six Flags so I don't really think either WDW or Uni is that great for thrill rides. But I typically don't count simulators as thrill rides. i think they both have a few good thrill rides. A couple more at Uni maybe. I think it's maybe more appealing to teens because the other rides and themed areas (other than Suess Landing) are geared toward a little bit older crowd (Marvel and Jurassic Park, etc). Many of the themes and secondary rides at Disney are aimed more at kids.
