Over the course of his career, definitely. This year, arguable.
Nene and Flo made the same metres, although Nene had marginally less runs and less minutes. Flo made more missed tackles and less tackle breaks. The biggest difference comes in the tries scores, but in context (playing outside Lafai, with second most offloads in the NRL, and Widdop, with the third most try assists, as opposed to McCrone and Aitken/Dugan) that is to be expected.
Of course, there's the intangibles to consider. Flo's lack of speed cost us tries, there's simply no getting around that - I can think of twice in the final game where he was in the clear, only to be easily rounded up by Chase f**king Stanley!! Compare this with Nene's perceived lack of effort.
One of these problems is far more easily fixed than the other.
