For me, stacked has a sharp breakpoint and lost od back end - a layout I prefer on most of my balls (I play rather slow, so length and a late reaction works well for me), esp. on medium conditions and with a high pin.
Label drill offers (relatively) more mid lane action. The ball revs up earlier and has a very tame back end, almost as if rolling out. Rather arcing, unless the oil is too short and the ball jumps because it hits friction too early. Good for control, IMHO better in this category than a stacked layout.
Another selling point: you cannot do much wrong with it. If you have no clue where your PAP is and if you are just happy when the ball moves, go label. You wont need a balance hole, anyway. Makes your driller happy, a no-brainer.
If you have a clean back end and want to see more ball action and a rather hockey-stick like hook shape, go stacked.
Besides, it is also important how far you place the pin from the PAP...
