Reliability, lack of errors??
I use this one:
Premium2
They say this about it:
PoweRec
Plextor Optimized Writing Error Reduction Control (PoweRec) adjusts laser power and writing speed so they're at the optimum settings for that particular disc. Using real-time monitoring of the write data, PoweRec can increase or decrease write power and speed to guarantee the best possible writing quality with whatever brand media is used.
Audio Master Quality Recording
To improve recording quality still further, Plextor’s PlexWriter Premium2 incorporates Yamaha’s Audio Master Quality Recording system. Users can create studio-quality audio masters that not only sound better, but can also increase the life span of their valuable recordings. In addition to reducing jitter, it can improve playback compatibility (for the widest range of players), increase the lifespan of audio CDs and backups, and protect valuable data.
