When in actuality, neither are "game changers" both are evolutionary not revolutionary. Both are an impressive collection of previously seen tricks. Both are great, but also have their faults.
There are very few actual game changers in this industry. Disneyland was a game changer by inventing the modern concept of a "theme park". WDW was a game changer by inventing the concept of a "Destination Theme Park Resort". FP was a game changer. Hogsmeade at IOA was a game changer by inventing the concept of the single IP land and by pulling the merch and F&B into to the theme. By definition, "game changer" has to change how the game is played.
Very few modern single attractions are "game changers". Pirates and Haunted Mansion were...60 years ago. Spider-man is truly the last "game changer" attraction that I can think of. I wish ToT was a game changer, but alas, no one seems to want to play that game. Which is sad because I love that ride. I don't even consider FJ a "game changer". It's a little bit Haunted Mansion and a little bit Spider-man with a cool new RV.
And I wasn't trying to single you out as a pixie duster. I think of you more as an experienced and observant theme park fan with a clear Disney bias. We all have our own biases. I, personally, am no longer a fan of slow moving RVs showing me repetitive robots that look like they are conducting an orchestra. It's like riding through an animated wax museum. Oooooo, exciting. Y'all seem to LOVE that, but meh. I am also over the simulator fall/catch gag. And I swear, if Universal spritzes me with water one more time...
All that said, I have ridden both RotR and Hagrid's 2 times each. And if you said I could hop on either right now, I would choose Hagrid's. It is just soooo much fun. I grin like the village idiot while riding it. The first time I rode RotR, I was jaw dropped twice. Once when the transport shuttle opened into the hanger, and in the At-At room. Unfortunately, that kind of "OMG" moment only works the first time. For that kind of "wow" moment I still prefer Gringott's Bank Lobby. It is just so beautiful, with the crystal chandeliers and inlaid floor. I don't even mind the vinyl wrapped columns.
