I've been running these for about a year now. They're as good as they get, short of long travel. From my perspective, they handle better overall compared to Kings. Like others have said, they're a more advanced shock. They have excellent bottom out control; no hydraulic bumpstops needed. Build quality is excellent. The Bilstein 8112's really shine at higher speeds, and larger dips. I haven't bottomed them out yet, and they've seen air a few times. I'm not sure about the ones listed here, but they (at least my set) are KDSS compatible.
I posted a little bit about them before in this post:

Not the best picture, but here's getting some air on my latest desert trip.
