I love my OxyCheq wing, as I've found it to be well shaped, durable, reliable, and more reasonably priced than comparable products from other manufacturers.
I owned a DR RecWing in the past. It was my first wing, and although I didn't appreciate the difference at the time, in hindsight it's the worst wing I've owned. I mostly attribute it's shortcomings to the manufacturer's attempt to make it good for both single tank and double tank diving. The compromises that required make it excessively large for single tank diving (55# IIRC) and prone to folding around the tank like a taco shell which made it unnecessarily difficult to dump, and also made it too narrow for doubles diving, which caused it to get pinched between the tanks and difficult if not impossible to inflate fully. I'd steer well clear of that wing, and get seperate wings for single and double tank diving.
