Is the Mace of the Insolent comparable to the Blue Flame sword?

I've read on various forums that the Blue Flame Sword for sorcery casters can scale insanely well (innate magic damage, magic infusion, and crystal magic weapon). If done correctly, this can be the second best catalyst in the game. I've had a really hard time finding concrete info about the Mace of the Insolent. From what I've read, it won't do as well on a pure lightning/dark build because it scales both of them. The best info I could find was people saying they would test it and post results, and that was a month ago with no results posted. Can the Mace of the Insolent with a lightning infusion be a viable choice for a pure lightning caster?
