Necropolis or Castle (Which one is stronger?)

I definitely really like the Barbarian theme as a proud, independent tribe that respects only the strength of weapons and the wisdom of their shamans. But I am disappointed with playing as them in Heroes of Might and Magic III (especially after Heroes of Might and Magic II). They were taken and completely ruined. It is almost impossible to play with them. They die like flies, you build Cyclops, but they are not very effective, and the ultimate unit, Behemoth, has a speed of 9. Of course, if you test them one-on-one, its ability to remove 80% of defense is great. But who would attack a tank with spears? Behemoth will be hit a couple of times with Implosion, and then he will just be a cool, strong guy who used to be able to remove 80% of defense. Add to this some unfriendly behavior of his fellow warriors (the abilities of all units are somehow unbalanced), and the Barbarians are generally useless, unless you switch to developing another castle (if you have enough time and resources). And if you play on 200% difficulty, the only way to fight is to start as a cart driver (Gurnisson). Then, they might not let you switch horses midstream (switch to Crag Hack). Conclusion: a proud, independent tribe that respects only the strength of weapons and the wisdom of their shamans, which embodies the principle: "It is better to be twice dead than to rot in captivity." And you can't take that away from them.
