If you tape and smooth it, and the wall is still moving (settlement), then it will continue to crack. If you caulk it, the caulking will move with the settlement for limited amount of movement. Caulking is easier, quicker, and if done right will look just fine. Use Dap 230.
The best thing would be to find out what is causing the movement and fix it. Obviously this is more costly. I've seen these movements open up to over an inch and then the repair is really costly.
