I use to be a full-throated Disney fan for my entire life, I much preferred them to the Universal parks, but I have to say that isn't the case anymore. Over the past decade Universal has undoubtedly stepped up their game, and as much as I credit Universal, I blame Disney for me becoming disenfranchised. Today's Universal reminds me of Disney in the 90s-- massive expansion, building new parks (ie. Volcano Bay, *pre pandemic* Epic Universe) building new hotels and continual updating throughout the parks. Disney just seems stale at this point. Yes, Disney spent billions on redoing DHS, but it didn't feel well planned like DCA's overhaul did. We got an OK Toy Story Land, management's crown jewel (Galaxy's Edge) and a replacement for the Great Movie Ride... call me crazy but DHS still needs more than that; and again there's no balance at the park; it doesn't need more E-Tickets, it needs fillers, and a water attraction (the only WDW park that doesn't have one). It's crazy to me, but Universal's parks are way more balanced than Disney's at the moment (outside of MK).
And while Disney has always cloned rides, Tron just feels lazy and Ratatouille is about five years too late; WDW's other trackless rides (ROTR, MMRR) are far superior, and like another member pointed out earlier, the Guardians of the Galaxy ride at Epcot feels very much like Rock 'N' Roller Coaster.
Disney is building roller coasters in huge (ugly) buildings while Universal is building elaborate outdoor, themed coasters... who would have thought!
In my mind there is no competition between Tron and Guardians vs. Hagrids and Velocicoaster; Universal hands down wins that battle, not only with the actual coasters, but the theming.
