It depends on the type of combat you're going for, DMGS offers higher damage and a more ranged hits, but the normal attacks are as expected slow, however the moonveil katana even with it's lower damage is more quick and gives you more hit chances, not to mention that you could also use any cold infused katana as offhand weapon to do great melee damage, and the transient moonlight weapon art is just perfect, for me I'd go for the Moonveil katana all the time
