The learning curve....
I don't use EAC so I can't tell you about it, but I did recently download it and one of the feature it did not have which I use a lot in Audiograbber was the ability to append ID3 tag info to WAVs. This allows me to rip CDs for encoding at a later time and not lose the ID3 tags
How ever EAC does have the ability to spawn any number of LAME encoding process in the background while you are ripping in the fore-ground - this is quite useful on a multi-processor PC.

What have you been previously using to rip you CDs?
