Deviling is great but tends to be more risky as in a general mob of monsters one may have some form of elemental attack. Raydric is just more reliable, you don't have to worry about more damage from elemental attacks etc. LoD I personally like, the only reason for that it because i usually run high vit or high def and the LoD is a good garment to complement that.
Ie: If your a flee sin, LoD isn't gonna help you much. : )
