I would suggest going on the manufacturers websites, there are many handy parametric tables (Try TI and ADI for instance).
There are two main types: successive approximation (usually high quality, high speed) and Sigma Delta which tends to be slower, though ADI and TI make some high speed, high bit versions.
If you are choosing an audio one for a design, I suggest looking at chips the sound card manufacturers use, they are often well documented, tried and tested and less likely to have supply issues.
it all depends on the requirements of the quality of the sound that you will require. Perhaps you can go to this link: http://focus.ti.com/lit/sg/slyb115c/slyb115c.pdf so that you will have a clearer picture of the critical parameters that you will need for your application. Not to mention that nowdays, designers will look for energy efficient chips.
