I wonder if the bitrate was the same with MP3 (ie 192k), how things would be? Both codecs have major and minor points right now.
MP3: + Better Quality at higher bitrates than 128K
- Larger file size than the MP3Pro files
- Depends a lot on the encoder used
MP3Pro: + Rather Smaller than the classic MP3
+ Near MP3 quality at high bitrates (80 / 96k)
- Needs specfic decoder for decoding
- Quality loss (at decoding) while making an Audio CD from MP3Pro
- Rather new method and not yet popular (like VQ)
- It could have higher bitrate options to choose.
- Not many encoders / decoders right now to choose.
Anyway the results will be seen in future...
