My first and only experience with Nero was ripping a badly scratched copy of Abbey Road. Nero ripped the CD successfully, and told me that everything went OK (no errors), but the copy I burned had numerous pops in almost all of the tracks.
When I ripped the same CD with EAC (using track mode, not image), there were multiple ECC errors on almost all of the tracks. EAC performed exhaustive retries on each error, and took several hours to finish. Even then, there were two tracks with unrecoverable errors. I then tried several things, including automotive paint swirl remover (not recommended) and finally recovered those tracks without errors. The copy that I ended up with is perfect in every respect.
I didn't spend time fiddling with Nero because it didn't have a fraction of the user controllable settings that EAC has. Also, Nero didn't detect any of the errors that EAC did.
I am guessing here, but I think Nero relies on your CDP to flag and correct C2 errors. My CDP reports that it supports C2 correction, but the EAC utility that tests your ECC logic indicated that mine did not report or correct known C2 errors. When that occurs, you setup EAC to bypass the C2 logic in your CDP and correction is done by the EAC software.
If you are ripping perfect CDs Nero will do a fine job. But if not...
