John French's Perturabo includes The Crimson Fist and Tallarn, in both of which he's.... angry. Angry and not particularly smart.
Haley's Perturabo explores his character in much greater depth and blends all that had come before into a coherent whole, where his shortcomings are deeply rooted in his upbringing, the way he was treated at home on Olypia and under the Emperor, and how his own martyr complex blinded him to his own deficits, his own antisocial behavior and the way he generally fails to make his voice heard.
In a way, he's in line with all the other Primarchs in terms of character flaws. Some of them even overlap with some of his brothers, as is usually the case.
Perturabo is just as much a product of his upbringing and homeworld's culture as the Lion, Russ, Angron, Curze, Guilliman, Sanguinius and all the rest. He was exploited and failed to learn the value of a father's affection, and carried the same prejudices (maybe rightly so) into the Imperium of Man.
And yet in Haleys, we have the travesty of a scene of him being a gullible, vain and ego craving idiot when Horus is showering him with praise and somehow convincing him he's different to all the others in one of the worst dialogues of the series.
I think DC is referring to the Primarch novella and not Perturabo in Lost and the Damned, which now that you've reminded me, is absolutely awful.
