Really a difficult question to answer unless someone has tried each of the boards. My suggestion for questions like this is to rely off of the reviews for each of the motherboards, this way you can see what people liked/didn't like about each of the motherboards. A good site to quickly do this is
http://www.newegg.com, many of the visitors there are experienced computer users who often buy computer parts and many write pretty good reviews on what they think about each of the products.
