Another factor not yet mentioned in this thread is the issue of midrange radiation out the port. Most ported systems have an open internal volume, and only a little absorbent material on the walls. This leads to internal reflections in the midrange that can enter the room through the port. With a front port these will be more audible than with a rear port which makes them diffuse and less directional. This is more of a problem with 2 way designs with their higher crossover, so the mid-woofer covers a lot more range. At higher frquencies you can also get port resonances, again more audible with a front port.On the other hand, a front port does give more freedom of placement. Such as near a wall, or in a bookshelf.
A rear port generally is a signal that the speaker is designed for placement away from the wall.
