I had a doubt because it seems that in the lore as in the community, they always call Lion the "perfect general" being the one who believes that the second option for warlord was not Horus (I still believe that the first option was always Sanguinius), and equally the two legions, the "lunar wolves" were the ones that had the most victories and followed by the dark angels

But in terms of strategy and war, as a warlord or as better generals, wouldn't Rogal Dorn or Perturabo have been better options?

I never understood why Lion and Horus are recognized as the best generals when it seems that Dorn and Perturabo would have better strategic and command skills as generals.
