Malthael is insanely powerful even before his two power up.
TLK has to cut someone to take it's soul. Malthael can kill anyone and take their souls without anything.
TLK was defeated by several guys and a large bunch of souls sure. But none of them equals the nephalem. Has said before by other people, the nephalem can cut through armys of demon without help anyhelp. There are nothing even close in the warcraft universe except godlike creatures. I harldy see TLK doing the same stuff as the nephalem.
All of this befoire Malthael powerup.
TLK has control over current death okay. But he has trouble to keep them at bay. His own spirit, Ner'zhul, His fathers....
Malthael Killed people by hundreds.
In a pure practical way. TLK is a heavy armor human with a sword as his best tool. Malthael can fly.
After his powerup, he has the power of all the dead combined in History and the power of the seven most powerful demons, TLK has the power of hundreds ? Thousands of death ?
Also, Malthael could wipe the entire world maybe I should have started by that.
