Just to add my 2 cents.....
I believe Bob is right in regards to cost - layers are higher cost than
vias. From a noise standpoint you may have more trouble with greater via
counts - your planes start to look like "swiss cheese" and you might even
isolate some areas of the plane if many vias are close together.
You will just have to take all the factors into consideration and
determine what's best for yours situation.
