The problem with Uni is pretty much all of their etickets especially at USF are screened attractions while at Epcot it's the attractions that are viewed as mediocre. When we are at Epcot we just usually skip the awful rides like Nemo, and so many of the films. It's hard to skip the main rides like Simpsons, Gringotts, despicable me, soon to be Fallon, Fast & Furious etc.
I love Epcot and Uni but they both use screens instead of sets to save money on most occasions, that's why Epcot is in the state it is. Imagine how outdated many of these attractions will be in 10 years at Uni.
It's best to have a balance. Take Shanghai Disneyland for example: dark rides, sets and screens ride: Shanghai Pirates (that's how screens should be done, used only on things where the ou physically cannot do IRL), rollercoasters, Soarin' Simulator, boat rides, omnimovers.
Epcot if you look at its main attractions: Soarin, Test Track, Spaceship Earth, Living with the Land and Mission: Space, (technically Imagination but it is still awful), and Frozen it's an outdated but relatively balanced line-up (still very lacking and that is why it gets so much criticism). Epcot's attractions lesser attractions Universe of Energy, the many films, Nemo receive hate and it is not ignored.
Epcot is saved by The Walking done throughout World Showcase & Fireworks, even thouh only a few rides are great (like 3). Universal doesn't have that, and since it seems that is all USF is getting in the near future that is problematic. Seems like a classic case of history repeating itself.
