Even balanced rackets have a balance point that is more or less near the middle of the racket making it all-rounded and well suited for most players.
The advantage of an even balanced racket is that it is suited for a wide range of shots and play-style.
The disadvantage is that while it is all-rounded, it does not excel in any particular aspect.
