    Maybe, but I've always considered whey protein to be better.

    Different proteins digest in different ways.

    Kind of, some proteins wont have as many complete protein chains. Soy does or is considered to have all of them.

    Different proteins will digest at differing rates. The most important this to remember is complete protein chains or at least have all the amino acids you will need for your body to construct the needed chains.

    Different proteins have different digestibility: http://en.wikipedia.org/wiki/Biological_value with soy being quite digestible and also producing the most protein per acre of any crop, making it very cheap. It is however not a complete protein, meaning that you will not get all the essential amino acids that you need if you only eat soy. Animal products are complete (and usually heavy on the branched chain amino acids leucine, isoleucine and valine that are good for muscle growth) but more expensive - 'cept milk and eggs and chicken livers.
    Whey has the problem that it is very easily digested (takes about 4 hours) so if it is your main source of protein you have to eat it throughout the day, like every 4 hours.
    Any kind of monotony in your diet leaves you open to malnutrition (probably on a small scale though) and since soy is a major ingredient in any kind of processed food today most people get more than enough (see 'cheap'). Protein supplements are good when they don't replace meals but supplement them.
