Ported is good if tuned to your vehicle properly and typically will hit harder, but only at a certain frequency, example it might not be loud until you hit like 80hz. it is also much easier to bottom out your subs. Sealed on the other hand is pretty fail safe, It will hit hard and sound much much better. Unless you are looking to go into spl comp, then go with sealed, it sounds good with almost all types of music too.
