I've got lots of CD's that have been backed up to lossless AAC. This is the archive.

I have a few music players, most do AAC, all do MP3. Is there any physical reason why I should choose one format over another, when i convert down for portable listening? I will probably go for 320 MP3, or the equivalent in AAC.

Thanks.

I haven't tried them at low bitrates, but I recently did some ABXing, aiming for transparency. While LAME MP3 was pretty much transparent at V3, AAC at a similar bitrate (170-180) was still easily ABXable, with both Nero and Quicktime.
It was only one sample so I can't draw any definite conclusions, all I'd advise is that you do some testing of your own to see/hear what works best for you.
Compatibility is still in favor of MP3, but eventually that depends on the devices you use.

BTW, here are the files I used for testing: http://www.mediafire.com/?p8t9786go1m4xda

Well, neither 10 samples is enough to draw any valid conclusion.

The good AAC encoder is always superior to MP3 at any bitrates for my ears. I have tried like 30 samples (dirty in home tests) and my findings are :

Apple LC-AAC and LAME 3.97/3.98/3.99
AAC 96 kbps is better than MP3 V5 ~128 kbps.
AAC 128 kbps is on par with V2 . Another listener reports the same findings http://d.hatena.ne.jp/kamedo2/20111029/1319840519
AAC 160-192 is better than V0-320 kbps.
