Yeah, if we're comparing Anaheim's PotC to Orlando's, Anaheim's is the best. It's, like, almost twice as long, and it has that amazing bayou room with the restaurant and stuff.
If they ever wanted to upgrade a stateside PotC to be similar to the Shanghai one, I'd vote for Orlando's to get the upgrade and keep Anaheim's original the way it is. WDW was all about innovation and the future and stuff, so I'd be down with seeing more of the tech-heavy stuff like the Shanghai rides show up at WDW, and then keep Disneyland Anaheim as close to its original format as possible.
There's so much space not being used in Future World at Epcot... I'd be SO down for them getting the new Tron coaster there!
