Add the strength and magic attack of both weapons, then add Oportunism and  Bloodlust to the equation and then multiply the Heaven's Key's figure by 1.25 and compare to the Framae Blades result. In my case Heaven's Keys outperform the Framaes, but I don't use any holy buffers. If you add a holy buff to the mix that might well tip the scale to the Framaes, but you'd want a buffer with Holy Pact though, since that lasts around 10 mins.
