Sony NEC Optiarc or Pioneer DVR111D

So which one is better (that is which one is prone to less problems) Sony AWD170 (the NEC optiarc) or the Pioneer DVR111D?

I hate Pioneer very much and I am now using the Optiarc 7170a.

I am going for the nec 7170 (branded as Sony AWG170) but why do you hate the pioneer, i’ve heard nothing but good things about it?

I had the Optiarc (the NEC one) here. Not bad, not great. My next buys will be PX-755As, PX-760As and/or DVR-112s. That’s for sure. An exotic alternative could be Samsung. They can scan, they make good burns. But are they great drives? I don’t know… :confused:
