I think your argument is exactly backward, and cherry-picking a quote from Russell doesn't really buttress your argument if you know the full philosophical background of these two. Russell saw Wittgenstein's brilliance early on and supported him in his work, but as he was near the end of his career and his mental faculties were on the decline, Russell found it increasingly difficult to understand Wittgenstein's philosophy. Russell in hindsight was the lightweight next to Wittgenstein's brilliance. If you want a non-philosopher's idea of outstanding philosophy, I would have pointed out Nietzsche instead.
