But most of the "ensure res" scenarios that have been mentioned already exist by using Death / Killing Blow plus Create Undead.

Hardly the same. There are alot more visual indicators someone has been created undead then corrupted. They can be told to act normal, they can still talk. As a zombie they cant run, as a corrupt they can so alot easier to get them to sprint off the battle field away from help.
