Hello.
Today, we will analyze why, among all the heroes in our favorite game, Orson is the strongest hero in terms of units. The comparison will be made with the most popular and well-known unit-based heroes: Haggeesh, Ingvar, and Laslo.
I suggest we take a look at the table:
For the analysis and comparison, the following units were selected: 
, 
, 
, with a count over 6 weeks, excluding stats from artifacts, and only including attack, defense, and hit points from specializations and the starting skill.
As we can see, the stats of the units are almost the same, with the exception of Laslo, but he has fewer units. So, if we look at the characteristics of each of the units, we will see that Orson's zombies have resistance, almost immunity, to mind control. In other words, zombies are better than all other units from the specialization because they cannot be controlled. The exception is Lucretia's vampires. But you can create more zombies than vampires, both with and without necromancy.
So, as we can see above, zombies are units with the same stats as all other units from the specialization, but they cannot be controlled. You can send any other army against their owner, but you cannot do this with Orson (and, to a lesser extent, Lucretia).
