True the BenQ can burn at 16x, but the total time for the burn is just about where the LG is at a 12x. I go through about 50 discs per week and have found that 8x +R's @8x gives me the best and most consistent results. And considering all the time to rip, shrink, burn, verify, scan and then pop into a player - a minute or two saved is kind of a none issue to me at least.
My Benq and LG both burn 8x in 8 minutes. The LG burns 12x at about 6:30 minutes which is where my BenQ is at 16x. The Benq with the speed patch however, is a great ripper, and this saves me 8 minutes (rip, verify) in what is normally a one to three hour process.
