Necropolis or Castle (Which one is stronger?)

Necropolis's level 7 units are nowhere near as good as Haven's level 7 units. As for the level 6 units of these factions, there have been debates about their strength for quite some time, so they are roughly equal in power. Level 5 – perhaps the Lich is a bit stronger. But not by much. Crusaders are strong, but they probably can't handle Vampires, although, of course, it depends on how you play; a double strike is no joke. Griffons are definitely stronger than Spirits. Archers are much better than Zombies, especially since they also have a double shot. Spearmen are one of the strongest units at level 1, while Skeletons, with their stats, are weak. True, there may be many of them, but here the Archangels will come into play, mowing them down because they don't have any other worthy target besides Vampires. I think Castle is better – that's why.
