Which is stronger, Death Harbingers/Banshees or Death Knights?

We're not discussing the level of my game or my opponent's game here. I already play well on the highest difficulty level, so there's no need to try Veteran difficulty. And if you don't like the idea of Death Knights, don't install this mod. It's a personal choice.

I apologize if my previous message offended you. Unfortunately, I reacted rather sharply to your opinion that Necromancers have nothing to counter Humans with.

However, with all due respect, I still believe that even after a radical change in the mechanics of necromancy, the Necromancers remain a quite strong faction, which will have arguments against everyone, and moreover, it has become much more interesting to play as them. And my firm IMHO is precisely because
1 it's more challenging
2 there is a need to vary tactics and strategy (the only correct algorithm for developing a hero, which guaranteed victory starting from the 7th week, has disappeared)

And replacing the undead with black knights will seriously disrupt the balance and make the Necromancers overpowered. What's the point in playing if you can make a lot of mistakes and still crush your opponent easily?

Peace?
