   No-coat Ultraflex. We use the 325 usually. Great product.

   Use this on your inside angles. It won't crack unless you have a serious structural problem. I usually use hot mud to embed, but a good all purpose will do.

   Edit: if you have noticable movement, I would consider removing some drywall at the corners and tieing them together, probably with some type of Simpson conector. You are going to refinish anyway

   My first inclination would be to cut in an expansion joint along the bevels.  That would corral the movment of the differing planes.  I'd then fasten a trim piece, like a 1x4 or the like over the joint, fastening it to only the one side.  Then, and movement is what it is, and does not transfer over into broken joints or materiral cracks.

   Depending on the dimensions, I'd also be inclined to bit the bullet and receiling the space.  Now, that willl sound like a lot of work, and it is.

   However, it's even odds that the ceiling is fastened directly to the roof framing.  That situation has a number of compromises built in (NPI) at the best of times.  Roofs move in complicated ways.  Drywall moves in very few, and with very tiny tolerances (1/350).  Setting a separate ceiling structure under the roof allows for many things.  Proper insualtion for one; structure that does not move quite so much, either.

   But, those are my biases; others' differ.
