Don't exist listening tests between Aften and ffmpeg, also don't exist between free encoders and certified DD encoders.
But I know at least 3 differences between Aften and ffmpeg:
1) Channel coupling:

So far the only significant difference I've found between the Aften output and the DD output is channel coupling. The bandwidth reported for DD is the upper end of the coupling range. Aften does not support channel coupling yet.

The ffmpeg encoder, developed with Justin Ruggles support, have channel coupling.
Maybe for that the cutoff frecuency is improved (you can check a Aften encode and a ffmpeg encode at same bitrate and the last one support more bandwith).
2) Stereo encode bug.
Aften have a little bug and mix the two channels (reported by me in Aften thread). The output FL have traces from FR input and viceversa. At very low volume but exist.
Bug solved in ffmpeg.
3) Some audio hardware can't decode properly Aften encodes.
Problem solved recoding to AC3 with ffmpeg.
