Best writing quality for DVD+R DL

Although I have tried to find reviews for different burners, I still don’t know which one I should buy. At the moment Optiarc AD-7201A seems to be a good choice but are there better choices when the most important criterion is writing quality for DVD+R Double Layers and the second important is writing quality for normal DVDs? :doh:

The Optiarc AD-7200A or AD-7201A are great dual layer burners. I recommend them wholeheartedly.

The only other choice that might be a little better is the Pioneer DVR-115D, but those have been discontinued and are hard to find. The newer model, the DVR-116D, has a number of “issues” at the current time, and I cannot recommend it.
