It could be interesting, depending on how far out from the building it goes and how much it costs. I have zero fear of heights.
I'd do the Skyjump if it was cheaper, or if they made it an actual free-fall instead of a controlled free-fall...but to do that, they'd have to change it into an actual bungee jump. Bungee cords stretch and break, and they need to be replaced on a regular basis. I had one of the cords break during one of my hot air balloon bungee jumps. They used a 4-cord bundle for jumpers weighing less than 200 pounds and a 5-cord bundle for jumpers weighing between 200 and 250 pounds, and that was for a 220-foot free-fall. 800-feet would be too expensive to maintain...
