Just my 2 cents worth:
What I have found is that if your CD is in perfect condition (no scratches), then just about any ripper will do a good job (including MJ digitally secure). However, for scratched CDs, EAC is the only ripper I have found that I can put the ripped songs directly into MJ without listening to them and be sure they are "PERFECT" - no glitches.
I tried MJ's digitally secure mode on some scratched CD's and found that in additional to taking quite a while, the resulting songs have many glitches in them. I.e. you have to listen to every second of every song to see if you need to re-rip. I don't have that kind of time! Granted this was a while ago, and I have not tried it since as I continue to use EAC. So, MJ may have improved. But, if I had to guess, I would say it still isn't as foolproof as EAC.
One other intersting note - I have seen EAC have some problems on REALLY badly scratched CD's (although they still play in an audio CD player). EAC got so many errors, it just couldn't correct them all. In that case, I have found that Feurio was able to rip the CD's with no glitches (and very fast too!). The reason I don't use Feurio on anything but those CD's that EAC can't handle (a very small percentage) is because:
1. The interface SUCKS!
2. You have to listen to every song you rip - Feurio may say no errors, but that is no guarantee.
But, hey - if you have a favorite CD that the kid decided to use as a frisbee - Feurio may be the only way to salvage it!
Just my experience - you're milage may vary.

P.S. No offense intended to MJ - I love it!!! I guess I just see EAC as a totally different type of product that complements MJ very well.
