I'm one of the few that think EPCOT Forever is a far better creative piece for a theme park nighttime show than Harmonious.
EPCOT Forever at least celebrates something. Harmonious, as stated earlier, seemed to lack creative direction in its final form. The original iteration of EF was far more enjoyable to me than Harmonious. But that's because I genuinely think Harmonious is a clip show without any form of storytelling. Yes, I get the concept. Yes, I understand what they were trying to communicate. But it falls flat. Not to mention that it was not properly designed for 360-degree viewing in its final form.
EPCOT Forever celebrates the past, present, and "future" of EPCOT with original music and scores written for the theme park itself (minus A Whole New World). I understand a majority of folks in the park probably have no idea what's happening or don't recognize some of the music. But the show was never intended to run more than once.
Harmonious was meant to be the new show for another couple decades.
Comparing the two seems apples vs. oranges because their intents differ. But for myself, EPCOT Forever will be far superior to that of Harmonious. With or without the barges.
