I agree with blockend. I've used matix some but I prefer CW or spot depending on the conditions and how I'm shooting. I shoot manual exposure almost exclusively so CW and spot tend to suit me better. If I were shooting in an automatic mode I would probably be more inclined to use matrix. I would say if you are not familiar with compensating or you don't have time in an action situation matrix would probably give you a higher percentage of good exposures. However, as blockend said, it's not good at high contrast scenes.
