All we have is anecdotal evidence saying that the Blu-ray drives tend to be slightly better built than the modern DVD burners. We haven't seen that many complaints about dying Blu-ray drives, but this may simply be a reflection of their lesser popularity due to people moving away from optical formats, plus the 300% higher cost of the Blu-ray drives.
Part of the higher cost for Blu-ray drives is the blue laser reading/writing assembly, but licensing is also a pretty big factor.
Many of us recommend the Pioneer Blu-ray drives as being both dependable and high quality writers. Those who really want to split hairs recommend the Pioneer drives built for the Japanese market, like the BDR-209J. If you are in the US, I'm not sure how you'd find a J model however. The regular 209 is easily found at Amazon or Newegg.
