MP3 players: MP3 or WMA ?

I just got a new car with an MP3 capable cd deck. I want to burn some cd's to take advantage of this capability. I especially like the fact that I can fit a large number of songs on the cd.

The cd player documentation states that MP3 and WMA files are supported. In order to choose the best format my criteria is that I want the best sound quality and the most songs on a cd.

Any advice as to which format to choose in order to satisfy my criteria?

Thanks in advance for your advice/comments!

MP3 ALL the way, it has a better and more richer sound and quality, it can be stored in smaller megabytes too, plus it's more commonly used in other applications beside your car, so you can use the cd elsewear too

This is my opinion from listening to both formats over and over again using the same song and equal bit-rates and similar sizes:

I noticed that WMA files have slightly more clarity than it's MP3 counter part. I was mainly listening to cymbals and other high-pitched sounds during comparison.
mp3 is the best format for music on a car you can actually hear the sound difference between mp3 and wma

If you make mp3 from your cds.you have to rip the music at a high rate.so it sounds clear. if you rip them at a low rate music will sound like crap.also depends what you use to make the mp3 with.I use jetaudio. its easy to use.and has alot of features to make your music sound great.
The MP3 and WMA formats are not that different, except WMA is much newer and better optimized. A WMA file using a 96KB bit rate sounds about the same as a MP3 using a 128KB bit rate. What this means is that you get the same sound with a smaller file.

People who are suggesting that MP3s are smaller are most likely confusing WMAs with WAVs???
MP3 and WMA are both well known formats, however MP3 has a slightly better sound quality.
MP3 is more widely used so definitely get MP3 although WMA does have slightly better sound quality because it is a newer form of compression.
