dbPowerAmp uses AccurateRip so accuracy of rips is the same as EAC. If you turn on all of the secure ripping options in dbPowerAmp, it can be even slower than EAC if the disc isn't in AccurateRip, or doesn't match AccurateRip. I will read the disc up to 6 times comparing the CRCs to give an accuracy confidence. With default settings, it rips twice, just like EAC. Error correction is similar.
EAC's error reporting is much better. I love having the ability to listen to the errors. A lot of the time I'll live with errors on really bad discs because I can't hear it.
My speed issues with EAC were just the conversion to ALAC using iTunes. I really couldn't do anything else on the computer while iTunes was converting. Ripping to WAV or FLAC was never a problem.
I switched to dbPowerAmp when a release of iTunes broke itunesencode.exe that EAC used to convert to ALAC. I liked dbPowerAmp so much, I never went back. Sure it's not free, but $38 isn't much. It's also $5 a year for access to 3 of the databases.
