First up the Snap Fit models. These are seriously good. The sculpts are interesting, full of detail and of the the high quality you expect of GW kits. The models themselves are incredibly easy to put together but also lend themselves to modifications with each piece scaled to match the new Death Guard models.
I assembled one set as pictured on the box but the other one I intermixed with my Dark Imperium Death Guard swapping arms and weapons around and adding a few bits left over from other sets.
