Fun question!
Some of the queues are really interesting and fun with great attention to detail - but as wonderful as some of them are, I would skip every single one if I had the chance!
My favorites are; MK - Haunted Mansion, Splash Mountain (it's long, but I like it!), 7DMT (if you can rope drop and go through the queue). Peter Pan is nice, but only if the wait times are low.
EC - Guardians looks like it will be the only winner here!
AK - FOP (it is worth walking through at rope drop or low wait times, otherwise... skip!), Everest.
HS - Tower (my favorite ever!). ROTR (it is cool, but skipping the line for ILL does not really cut out anything interesting, IMO.).
The queues which bring me the most misery are Magic Carpets of Aladdin, Jungle Cruise (it just goes on f o r e v e r!), Remy's, Frozen (I have never queued for this ride, I always skip the line - but everyone looks miserable!), Na'vi River, Mickey and Minnie's Runaway Railway, and literally every show that you have to wait in a holding room with everyone else.
