Can some of you shed some light on what you consider the chief differences between red and white oak? (Are there others available? Black, maybe?)

I know there is a color difference but for those of you that have worked both, what did you find you like/disliked about each species?

My wife has suddenly discovered quartersawn oak. She was never a fan of flatsawn oak and therefore not an oak fan but she saw a qs oak kitchen display at the San Jose Home/Garden show yesterday and was like, "What is that wood? That is pretty cool!" She was shocked to find out it was oak and learned something about how lumber may be cut from logs and how it can look very different.
