We stayed in the 90's building and was able to see the fireworks from EPCOT. I guess it depends if you want to be close to the food court or not. I think there was only one building further then we were, but I enjoyed getting the refills of coffee/hot chocolate each morning while the family woke up.
If you don't mind the stairs or waiting for the elevator, I would recommend getting the top floor. This way, no one is above you, thus no way to get a noisy neighbor above your room.
