General consensus seems to be that it's better overall, and also doesn't have the build-quality issues the 716A has. A good buy
One gripe is that it only has 2MB of buffer compared to the 8MB of the 716, but frankly it don't make any difference at high-speed anyway; Worry more about having a working BURNproof!
So far, the only real bad thing about the 760 (And also the one reason why I haven't got one yet) is that it only works fully in Windows+PlexTools - For some reason Plextor have changed from their traditional openness and tried to lock everyone out of all the extra features of the drive, so nothing can access them except PlexTools, not even Nero et al.!
