There's the annoying stereotype you sometimes see where people are like "Oh, Stalin wasn't smart, he was a brute who only rose to power through violence and coercion" b/c when you read anything he wrote, he shows a clear understanding of his subject by making very careful, easy to follow arguments that explain the concepts he talks about concisely. Obviously you gotta hand it to the kind Vladimir Ilyich but for me Stalin might actually be more enjoyable to read
