Hmm well there may be some advantages in being able to view the exposure and histogram before you take the shot, and the other possible advantage when you aren't necessarily able to hold your eye to the finder. For certain macro shots, or low-light situations, it can be very handy if you dont own an angle finder my own preferred choice when the standard bright and clear viewfinder still wins hands down..
