1. dunno if i'd call it better necessarily, but it does have a few features that some prefer over your standard gotoh
hardtail bridge. for one thing, there are no sharp corners like there are on the saddles of the hardtail. it has quite a bit more mass, so that arguably is going to sound different than a hardtail string through (as well as that fact that the stings do not string through the guitar). imo, it's all preference and i prefer the old school hardtail, but to each his own.
2. no, not individually adjustable, just the 2 big screws on the end. but it is radiused to be perfectly aligned with the wizard profile.
