Rich-n-Tone seems to have the best reputation that I hear of. I stick to the cheaper calls for ducks. We get the first cracks at them up here so you don't need to be a pro. I've found that overcalling is usually an overkill, so I usually stick to a few highballs to bring interest, and follow up with a lot of chuckling (we do a lot of field hunting for ducks).
Single reeds for volume, double reed when they get in close. That would probably my only preference for one or the other.
