For those who shoot casually I like the WB, as she is nearly bullet proof when properly tuned. For those who shoot a lot of league one may lean towards a drop-away. The drop away can be a little more difficult to get properly tuned to my standards. Yet when the right, drop away is properly set-up. She will be very forgiving in the shot and no fletching issues will result as a result of interference with your rest.
On the other hand I would shy away from shooting groups when using a good drop awayas the robin hoods and pierced fletching may get expensive.
The Drop Zone is one that I have not tried. As many have commented on the difficulty in keeping this rest quiet. My favorite rest to date is the Zero-Effect sold by Muzzy. The Turkey claw on the ZEis nearly as effective at containing the arrow, as is the WB. The containment is very important when hunting.A little moleskin in the right places and the ZE is as quiet or quieter than the WB IMHO. Sorry to deviate from your original choice yet I just would not feel right if I did not mention the best options.

Personally I would recommend both. A fool proof WB to keep things simple when getting started. And a quality drop away down the road as your proficiency will benefit from an even better arrow rest system. Everything mentioned above is just MHO.
