If your cameras come to rest before the end of the scene, you may find it more powerful to stick with one shot when you come to edit. Cutting between the two shots after the movie is over can seem a little forced. On the other hand, cutting out of the scene while the cameras are still moving feels like we're leaving before the conversation is over. Ideally, the camera should come to rest just a couple of beats before you want the scene to end, so you can stay with one shot for a moment, and then cut.
