It's easier to untie. Has a cool method of tying. When a loop is loaded the knot becomes a bend. The alpine butterfly forms a secure bend, while the flat figure 8 can capsize at low loads.

I would use either for a directional load, but only an alpine butterfly if loading the loop is conceivable. And using the flat 8 as a bend is suicidal.
