It's an extremely fierce competition between Stalin, Hitler and Marx. Everyone else is simply a moron in comparison, don't even bother with them.

Hitler made the biggest blunders in practice (invading places he shouldn't have etc.)

While Marx made the biggest ideological blunders (muh collapse of capitalism and all conflict is material/class conflict, despite ethnic conflict being the only constant throughout human history)

Stalin is a creepy, unnerving bastard, and was borderline omniscient at times in the war. Don't fuck with Stalin. If we're going purely by results here, then Stalin is by far intellectually superior to all others, albeit communism is a shite ideology.

Hitler had roughly 16k books in his personal library, I am not joking. 8,000 of these books were military related. It instantly reminds you of a chud who spends half of his free time playing HOI4. Hitler trained his memory throughout his life, and would always focus on the essence of a thing, and fix it in his mind.
