I'll trade a working setup over clutter any day. Seriously. Do not underestimate the hassles of keeping drivers up to date, or the time you'll waste trying to figure them out. Yes, it would be nice to have things simplified. But, as Einstein once said, "Make things as simple as possible, but not simpler."
The complex part of zones is the software, so keep that simple by using one-device, one-driver. Going with a multifunction device requires the driver, the operating system, and the software to all "do the right thing". I've learned not to trust all that.
