BenQ DW1670 or Sony DRU-820A firmware?

I had purchased a I/O magic DW1670 @ Staples some time back and it had OEM firmware 100 (the drive name was listed as “ATAPI DVD DC 16X8X5”). I then recently updated to the 103 firmware from the BenQ website using the MCSE tool (the drive name is now listed as “BENQ DVD DC DW1670”).

I searched through many posts on this board related to the DW1670 & the DRU-820A, but did not come across anything that would suggest that the BenQ firmware 103 is better than the Sony 1.0c firmware or vice-versa.

Is one better than the other? Any thoughts?
