USJ definitely has a great parade that puts most parades, Superstar, the sorry thing they pass off as a parade. CineSpec is nice, but could be so much more (better than Uni360, but then again that's a really low bar).
The main thing is, live entertainment/shows aren't in UOR's wheelhouse and it certainly doesn't appeal to their audience as much as a Disney-going audience. Not to mention land is very valuable in Orlando for attraction space and we end up with what we get.
Where Uni excels with Entertainment is when they are dealing with events. Mardi Gras, HHN and even Christmas (Sea World is still the best in Orlando when it comes to this imo) is very good. Daily entertainment however is a bit lackluster.
