SSE and Rio Del Tiempo are rides with no wait like ever that have highly sentimental value to me and are two things I will ALWAYS associate with EPCOT Center, much like WoM, Horizons, and the original JII.
Soarin' is an amazing, relaxing ride, although I wish it were longer considering the hour+ minimum line that almost screams "Fast Pass or skip" It's great but it's over so fast and the lines are sooo long.
AA is moving as an American personally and historic and another EPCOT Center attraction, not a merely "Epcot" one...
Test track is fun and long, but prone to breakdowns and huge lines +it killed WoM which was always my fave as a kid.
EEA is one of the few changes from EPCOT Center to Epcot that I actually see as a plus (Other than Eo to HISTA...and MAYBE KK/FR to Soarin' although I loved those shows dearly) It's long, relaxing, and entertaining.
Maelstrom and M:S are fun but imo mediocre. If M:S didn't kill Horizons it may have gotten more points, but it's basically a suped up motion simulator that is way overhyped. Maelstrom may have scored higher but typically long lines for a relatively short ride and I rarely want to burn a Fastpass on it so end up in standby for 20-30 minutes.
The Land Boat ride also has sentimental value, but the removal of "Listen to the Land" music has tarnished its score. I don't know what it is either but I don't feel as captivated by it as I used to when I was younger -plus this one tends to get big lines too.
HISTA - It's a great 3d movie, probably my favorite behind Philharmagic, but it's dated in a bad way. SSE and Rio are dated too, but they're both more sentimental for their colors, and figures, and scenes - whereas HISTA is just a movie to attraction attraction based on a movie from the early 90's which had a series of rather awful sequels. Nicky is probably in his late teens by now, does anyone else realize that? And the dog that played Quark is probably long gone...
JIYI - See above note...
