I recently used SNAs for a five night award stay where my upgrade odds were probably good but the base room sounded small and unappealing. SNAs failed to clear on my paid stay a few days earlier.
I also had SNAs fail for a five night award stay but got a free Plat upgrade at check in to a suite that was about the best I would have gotten with the SNAs.
My conclusion: YMMV
