I notice an incorrect entry on your ripper comparison chart: xACT does NOT have a "verify suspicious sectors" option, nor does it verify them.
Also, xACT does query Freedb (you can see it on the log), although it will not actually title the tracks on output. One problem with xACT is that the developer made it a "run only" application, so you cannot edit the app. I believe this may be a violation of the cdparanoia GPL, but what do I know?

Pepzhez I will change Mac CD Ripper Comparison Chart to reflect the fact xACT does query Freedb placing the info in the log only after the rip is completed and currently does does write tags to outputted files. I will clarify that xACT does not verify suspicious sector but does report problem sector % in the log, I did not make this clear getting lazy! Thanks for the correction.
