I've been the the Shedd, but don't really remember it being anything special.
I'm really impressed with the Oklahoma aquarium. I went to visit my parents in Tulsa so we checked it out. I had no expectations, but it's really nice there. They have diverse exhibits, a lot of large local tanks, and a complete wing of tropical, sub tropical. It's arranged to group the animals nicely as well.
I got to scuba in the epcot aquarium a few years ago, that was real fun.

GA and TN aquariums are supposed to be among the best.
I was thoroughly impressed w/ the Epcot aquarium (>10 yrs ago). Sea World's Orlando walk through & other exhibits are nice too.
