Scanning/reading question

I have two LiteOn drives:

SOHC-5232K 52x32x52x CD-RW & 16x DVD-ROM
SOHW-812S 8x DVD+/-R Dual Rewriter

I usually rip DVD’s from the 5232K and then burn with the 812S. Should I rip and burn with the 812S only? If so, what are the reading/ripping advantages of the 812S vs. the 5232K?
