If you want low deep bass, you can tune the port to around 25 HZ or if you want loud boomy bass you can tune it to 50 Hz. This is the main advantage you gain with going for a vented design.
Sealed box: This box is more smaller and more easier to build, in fact its also more forgiving if you make a design error. Built right it will provide far more better bass response vs a ported sub box design. The bass more known to be tight and punchy, which adds a nice feeling to your chest with your music.

It all depends on what your listening tastes are like and the type of music you play. If you like big ear deafening loud bass that shakes the ground, then a ported box is for you.
