I've used Chris King, Mavic (pawl and spring) and DT Swiss hubs:
Chris King - Generally worked well, but could be finnicky and Chris King recommends their special grease for servicing (at least they used to). I would ocassionally have the hub slip when I mashed the pedals. This was ten years ago, have not tried anything recently, maybe they are improved.
Mavic - pawl and spring. If you don't stay on top of servicing my hub made a terrible noise when freewheeling. Kind of a pain to service. Otherwise worked fine.
DT Swiss - I've been using both 240 and 350 hubs for the last ten years, tens of thousands of miles. Love them. Trouble free and easy to service. When you hear them getting louder on freewheel, just clean and lube to quiet them down.
