BenQ 1620 or Samsung S203N for scanning?

Hi

Ive just got myself a new writer, Samsung S203N and I am wondering which drive I should use for scanning or basically which of the 2 drives are more reliable at scanning.

Also, for comparison between the Samsung & BenQ do I need to change any settings in Nero DiscSpeed, in particular the scanning interval. I think the BenQ uses 8ECC whereas Samsung uses 1ECC?!

Comments much appreciated.
