Best CD burners for quality writes?

What are considered to be the best CD burners for quality writes (not speed)? Either as CDRW or DVDRW drives.

Writing quality is related to the combination burner/firmware/media.

With high quality media, almost any burner give excellent results. Regarding firmwares, each drive have the better one, and sometimes latest is not the better (see benq 1640 as example). Too bad only doing some tests it can be found what is the better.

Maybe Plextor Premium is one of the best CD burners. DVD burners can write with good quality CD media, but the best results can be obtained only with CD burners.
