For those who are comparing launch angle and spin from various drivers, are you using the same shaft? The clubhead (apart from loft) has very little to do with this. They can manipulate the sweet spot through weight distribution, and increase face speed through materials and design, but launch angle and spin are going to be functions of shaft properties and loft.
As for those who are knocking the adjustability factor as a crutch.... I agree that people should have solid golf swings. But compare Matt Kuchar (flattest swing ever) and Colin Montgomerie (most upright swing ever). Both are excellent golfers, potentially HoF. Both (I'm sure) have adjustments made to their clubs to make sure the equipment is enhancing what they do well, not limiting it.
All that adjustability does is bring this same level of customization, previously available only in tour vans, to the neighborhood pro shop. Most of us could benefit from one degree flatter or more upright. Few of us have the resources, time, or patience to hit ten shots with a driver, then bend it, then hit ten more shots, then bend it back... ad nauseum. You shouldn't be setting your driver 5 degrees closed to cure your slice (it's easier fixed by changing your grip and stance, anyway). You should, however, make minor adjustments to your club setup so that you're starting with the club well-soled and square.
