You are grossly over-simplifying Karma. Serving a similar purpose doesnt mean he is a living version of Karma. That is almost like saying a sword is the same as a shuriken but better because they both cut. Or that Kirin is the same as Chidori but better because they both use lightning.

BZ is a far inferior method than Karma.
 * For starters, BZ cant bring Kaguya back to life.
 * Black Zetsu cant transform any suitable host. Or any host for that matter.
 * He doesnt awaken Kaguya upon her death. He actually needed centuries to set up the circumstances necessary to awaken her
 * There is a possibility of stopping Zetsu.
