I don't see what's so special about the Jaden Rose. I've played a 2127z, and they're outstanding. The carve on the body is comfortable, and you gotta love the extra-wide scoop on the horn. The Edge Zero 7 is also, in my opinion, pretty much as good as it gets when it comes to trems. Supremely comfortable, easy to use, and buttery smooth.
Plus, the basswood on the Prestiges is not some cheapo wood. It's very resonant. And pickups are pretty easy to swap out, though I didn't mind the stock ones in the RGD myself.
