My turn to be a contrarian.
Went into Potter-IOA a couple years ago with high expectations. It came in well below those expectations. Hogsmeade Village and all its features are outstanding as expected. Then you exit the Village and face the school and the entire right of your direct frontal view is the exposed show-building (and further right the coaster tracks). I had known of this issue but couldn't believe the unthemed showbuilding would be so dominant in the money vista (the equivalent of Shanghai Tron, but less forgivable due to Potter's Scottish Mountains setting). Then comes the FJ queue and things are outstanding again (although Uni goes way, way overboard everywhere in their plain Exit signage... a contagion that WDI is catching). But the ride experience itself... for me it was too chaotic (not physically, but in sequence of events) and the transitions from screen to set were very unconvincing and jarring. My assessment: Potter-IOA land is far from the "hyper-immersive" realm (outside of the village) that it gets credited for.
Potter-Diagon Alley, on the other hand, did meet our high expectations, including the rides. No glaring backstage issues (though similar exiti sign problems). Maybe because there weren't as many sets, and thus jarring transitions, meant Gringotts felt a much more complete and believable experience. Loved that ride.
My point: Wizarding World-IOA is no high bar to pass... a couple dozen existing lands around the world's top tier parks do immersiveness better, including several at Animal Kingdom. From an environment stand-point, I found IOA's Port of Entry to be technically more immersive.
