Should I convert all my audio to 256 AAC?

Hi all, I'm currently researching what the best route is to go with when converting over my CD library. I realize that everyone loves Lossless (which I'll use for archiving the CD's) but I'm looking for "the best" lossy encoding.

I was originally planning to encode all my CD's into 320 CBR but it seems that almost everything I read states that this is a waste of space as their is nary a difference (except to the most trained ears) between 320 CBR and VBR v-0. Ultiamtely, I don't mind the difference in space when on my computer hard drive but it does become more of an issue when uploading to my iphone for portable listening so then I switched course and started thinking I would go with VBR v-0 (I posted a similar question to this in the mp3 forum) but now I'm reading that I may even be better off going with AAC 256?

This may make the most sense for me being that I'm a Mac user (imac, iphone, ipad) and I'm going to playing all my music out of my itunes library.

Is there any reason I would regret the decision to go AAC over mp3?

Also, for those with experience with this, could you direct me to the best possible setting to use in XLD for encoding CD's/FLAC files to aac?

Two years ago I chose Nero AAC -q0.65 (via dbPowerAmp) for portable listening (TMo Vibrant and a pair of Yuin PK2 earphones), after having done some ABXs with similar bitrate VBR Lame encodings.
I'm happy with it, I barely notice any artifacts (mostly blues and jazz) but on some classical music files.
Needless to say, the advantage over my old LAME 128kbps CBR files is obvious.
I guess you could come to different conclusions, so you'd better do some blind tests with different encoders (and music genres) at similar bitrates.

Yeah, the thing is that I have a LOT of music to convert....and it's not just converting but properly tagging with artwork and putting it in the exact format I like within the itunes file/folder structure so I'd like to avoid having to redo anything by researching the topic beforehand.


I know what you mean, that's why I wrote a Bash script that parsed my thousands old 128kbps mp3 files ID3 tags and wrote them into my new aac files. I found a way to copy jpg covers too, but I can't find that version of the script atm.
Hope it helps
CODE
#!/bin/bash
#script per copiare le tag da un file mp3 nel file m4a con lo stesso nome
#script for id3 tag cloning from mp3 file into an m4a AAC file with same basename
#flapane.com 24jan10

for file in "$@"
do

title=$(id3v2 -l "$file" | sed -n '/^TIT2[^:]*:[[:space:]]*/s///p')
artist=$(id3v2 -l "$file" | sed -n '/^TPE1[^:]*:[[:space:]]*/s///p')
album=$(id3v2 -l "$file" | sed -n '/^TALB[^:]*:[[:space:]]*/s///p')
year=$(id3v2 -l "$file" | sed -n '/^TYER[^:]*:[[:space:]]*/s///p')
genre=$(id3v2 -l "$file" | sed -n '/^TCON[^:]*:[[:space:]]*/s///p' | awk '{print $1}' )
bandorchestra=$(id3v2 -l "$file" | sed -n '/^TPE2[^:]*:[[:space:]]*/s///p')
composer=$(id3v2 -l "$file" | sed -n '/^TCOM[^:]*:[[:space:]]*/s///p')
#publisher=$(id3v2 -l "$file" | sed -n '/^TPUB[^:]*:[[:space:]]*/s///p')
#track=$(id3v2 -l "$file" | sed -n '/^TRCK[^:]*:[[:space:]]*/s///p')

#echo $title
#echo $artist
#echo $album
#echo $year
#echo "$genre"
#echo $track
#echo $bandorchestra
#echo $composer
#echo $publisher

filemp4=$(basename "$file" .mp3).m4a

mp4tags \
-s "$title" \
-a "$artist" \
-A "$album" \
-y "$year" \
-g "$genre" \
-R "$bandorchestra" \
-w "$composer" \
"$filemp4"

done
