The prime advantage of Ginther's Rift is its very high added magic damage. Enemies do not have Resistances to magic damage, so Ginther's Rift will generally always do a large amount of damage to opponents. This high damage is also supported by the high Attack Speed of Ginther's Rift, making it both a fast and powerful weapon.
However, the rest of the properties associated with Ginther's Rift are minimal at best. In Nightmare and Hell difficulties, magic damage is too high for the magic damage reduction of Ginther's Rift to be effective. Still, it may be enough to prevent dying from one hit.
Ginther's Rift repairs itself every five seconds. This is actually a fairly useful ability, and can help save gold on expenses used for repairing weapons. In addition, the repairing speed allows for an ethereal Ginther's Rift to be fairly useful for those lucky enough to find one.
