Well the real important thing, which you're all missing, is that Bilge Rat Barges is better than both of them! :hat: It has the thrills, gets you utterly and comprehensively drenched, and has awesome theming.
Slightly more on topic though, I really feel like Dudley's time must be up at some point soon. It's just become an anachronism when you consider the quality of everything else in the parks. I know supporters will cite the 2 hour queues it still gets on peak summer days, but I would put that down to desperation rather than any indication that the ride itself is actually 'good' by Universal standards.
