I made an MP3 VBR that hovers between 160kbps and 224kbps with lame. Then I made an Ogg Vorbis file with the default settings. Winamp displays the bitrate (VBR) between 155kbps and 202kbps. The track was made from a 10min 18sec WAV (103MB). The MP3 file is 15,759,612 bytes and the Ogg file is 12,827,676 bytes.

After listening to both a couple of times, I think that the MP3 sounds brighter. This may be because of the higher bitrate range, but I don't care because we're only talking about saving 3MB. It took about 5 minutes to encode the WAV to Ogg on a PIII 850 in Win2K.
