Better sound- finer control, etc. Not to say you have to buy the best to get good sound but the more you spend and take the time to really learn how to get good sound- mic placement, etc the better you'll do. Personally I don't use a field mixer as I'm usually just working with a single mic at a pretty consistent vocal level. However once you start recording multiple mics and dealing with varying levels a field mixer will help you get better sound.
