The tires only have so much traction at any given point. When you power all 4 full-time, you limit or curb the lateral grip they can provide. Therefore ideally you want the fronts doing the turning and rears powering until the rears slip.

This is why two of the best AWD sports cars are mainly RWD cars that *can* send power to the fronts when needed (AKA GTR and 911). While cars like Audi's and Subaru's typically suffer from massive understeer yet they power all 4 tires full time.

Another small benefit to not powering the fronts all the time is an uptick in gas mileage.
