Write quality: PX-716, BW1620, or 3520?

All right...I've read the reviews. But, given the huge improvements to all three drives with the latest firmware, they're not all that helpful now

Boil it down: using high-quality media (TY, MCC), which drive will offer the best write quality at the media's rated speed. Speed is not really an issue.

I know the 1620 was considered the best for overall write quality for awhile, but has the Plexter caught up yet?

Frankly, if you're going to be burning those medias at their rated speed only, I doubt there is much difference between the three drives.
