Depends on what you want it to do. Sealed boxes are less efficient, meaning they require more power for the same output. Sealed boxes dig deeper, but often take much power to do so. Ported boxes can give as much as a 3 dB increase at the tuning frequency, but have sharp rolloffs below that point. A poorly designed ported box can actually damage woofers if abused. When a woofer plays below the tuned frequency of the box, it decouples from the enclosure. The sub is basically running in free-air. The suspension of the sub has no control over the movement of the cone. This can lead to over excursion and damage the woofer. Ported boxes can be a bit boomy at or very close to the tuning frequency. A well tuned and constructed ported box can give very pleasing sound quality, though. My slot ported box for my 12W7's, tuned at 37Hz, fucking killed at the metal music I listen to. It was also very musical.
My first box for my 12W7's was slot ported. I ran with that for about 6 months before I decided to go sealed. I prefer sealed boxes because the excursion of the woofer is never out of control, even at the deepest of lows.

I was always told sealed was better, and the box bought off a friend just happened to be sealed
