Not really tried the Beastmakers in earnest - just a quick play whilst screwing them on. A preliminary impression is that the Crushers are easier, a tad more incut and you can thumb-pinch the corners. The contact surfaces of the Beastmakers are very curved, both along the top of the hold and in cross-section; they are too shallow to get your fingertips behind so I was reduced to full crimping the apex - just tips of fingers in contact.
