At it's best, EAC is slower, but will make a good job of getting the best out of originals in somewhat used condition, and allow you to easily check the points where it MAY have found a problem (often they are clear) and to eliminate some digital glitches if there was a problem.
It also helps if you know your drive, and set up for it.
If your drive supports "Accurate stream", that's good - in fact, if it doesn't, get another drive to rip with.
If your drive "caches Audio", that's BAD, as it means EAC has to flush the cache with surplus reads, in order to read the wanted part twice for comparison.
If your drive supports "C2 error information", then you can avoid the double reading for comparison, but if the drive has very poor C2 accuracy, some errors could slip through unchecked.
- It's best not to use C2 for correction, as few drives are accurate enough.
The other issue, is speed....
Some drives work well on high speed with automatic reduction, while others will throw far fewer errors if you run at 1x on anything that isn't perfect - I've always favoured the 1x rip.
