Bertrand Russell’s Political understanding was poor to say the least. He was in no way an expert and seemed to have only skimmed summaries and a handful of short texts when it came to Marx, sounding more like Jordan Peterson fixating on terms. For example, I think at one point he spent several paragraphs fixated on “nothing to lose but our chains” without understanding the basic thesis. His criticisms were, therefore, basically a series of errors and misunderstandings rather than insight. And beneath it all, a distressingly consistent current of chauvinism and racism, even with his anti-war stance.
Russell is good for math, logic, and some analytic philosophy, though.
