Much better against the typical tdk, memorex, maxell dvd+r's. In recent batches I've tried of all three brands, they've all used the same CMC-MAG mid and have all scanned much worse than the MCC-004 based Verbatims, relatively speaking.
That said, initial scan may not make so much of a difference as long as you have no problems reading. Longer term reliability is more of a concern. Although with both types of dics degrading at the same rate, you'd expect the one with a better initial scan to fare better over the long run as well. Anyways, while I don't know much about dyes, that's what the AZO dye is supposed to help with as far as I know.
