Slow (7) vs Normal

I have two weapons my Pally can use in the future; a 3rd UG 2H BW (Normal) with an attack of 99 and the other is a VIP 2H BW (Slow 7) with 122 attack. If I hammer and perfect scroll both of these, I would have a 144atk and 167atk weapon. The difference between the two speeds is roughly 1.07x. Now my question is, which weapon would be better in the long run?
