Maybe not in technology but I doubt if the Potter ride is as
cute,
happy, or would make me feel as
"Warm and Fuzzy" inside as my Disney favorites like Splash Mountain and It's A Small World!

And those happy qualities, (that some more "jaded" fans enjoy making fun of), found in truckloads in my fave Disney attractions, are why I've always preferred Disney over Uni. For me, it has absolutely NOTHING to do with which park has the most, "latest and greatest" high-tech toys in their attractions!
Also, I'm not a big Potter fan. I enjoyed the first 3 movies OK, but the last three were WAY too dark for my tastes and all had sad endings. Whereas the Disney characters, stories, and songs found in the parks from the Disney Animated Classics (as well as new ones created for the parks like Country Bears and Figment) are my favorite characters, stories, and songs of all time!
Yet, I'm not a "naysayer" about Potter. I'm just not in a big hurry to go experience it, but I will get around to it eventually. I've never been a big Uni fan (although I do really like the ET ride!), so it'll be interesting to see what effect (if any) the Potter ride has on my decision to forgo a Uni AP and just stick with my WDW and Busch Gardens/Sea World APs for the portion of the year I live in metro Orlando.
I'm not posting this is an argumentative way. I'm just presenting a point of view that explains why at least some Disney fans like myself are not all that excited about Potter.
