Necropolis or Castle (Which one is stronger?)

I believe that Necropolis has the following advantages: 1. In the human castle, archers are level 2, but in the necromancer's castle, they are level 5 (although the price is accordingly higher). 2. Death Knights are better than Cavaliers, thanks to the Double Strike skill. 3. Vampire Lords... No comment. They have practically no rivals, except for Conflux and their own kind. 4. Ghosts drain mana - this is very helpful against powerful wizards. And in the end - Lich's cloak, Expert Spellcasting, and you become an Executioner!!!
