As Arny will confirm, 256 kbs is definitely distinguishable in mp3. How
does AAC perform at this bitrate?

In my experience, AAC tends to be better than mp3 - I'd expect 256 kbs
to be pretty good, though I wouldn't be surprised if differences could
be detected in some cases. Still, it's much better than 128.
