McFeely's catalog has some explanations. I've found it informative.

I don't know of any comprehensive discussions by any outfit that doesn't make or sell screws.

To my way of thinking, square drive is most convenient in difficult locations because the driver can easily carry the screw, Torx (the "star") drives most reliably, Phillips is ubiquitous, the rest kind of suck in one way or another.

Abby,

Although not quite what you were asking, the Summer 2008 issue of Woodworking Magazine has an article that compares several types of screws along with their various attributes, such as head design and thread style. It might be worth taking a look. HTH.
