My bad. I was confusing AAC per se with iTunes AAC-encoded tracks with
DRM.

Only at lower bitrates, viz. the hydrogenaudio tests

. And MP3 does work on more platforms and devices than AAC.
From the soundexpert pages, it is not clear that any of the top performers
are signficantly different at higher bitrates. Below 128 , AAC is
usually considered a safer choice than MP3.
What's being encoded also matters, e.g. a person here ABX'd AAC artifacts
on a couple of tracks at ~220 VBR.

AAC's Hydrogenaudio wiki page is here
