haven’t listened to this yet myself, but this podcast might help to evaluate Reitter as a translator:

Paul Reitter, a Professor of Germanic Languages and Literatures at Ohio State University, discusses his recent translation of Volume 1 of Karl Marx’s Capital with host David Staley. Reitter discusses the nuances and challenges of translating Marx’s work, the intricacies of Marx’s theories on value and capitalism, and how Reitter’s translation aims to preserve Marx’s original meaning and literary style. Staley and Reitter also cover the broader implications and significance of translation studies, the historical undervaluation of translation in academia, and Reitter’s future projects on translating the remaining volumes of Capital.
