I had more of a feeling, derived from others as much as myself, that those two were on par in terms of quality but flip sides of the same coin - sly's peak in the early sound, then a profound but equally moving reinvention. If anything, more significant to me that certain other albums tend to be overlooked in favor of those two, e.g. Life and Small Talk, though it's surely debatable which Sly albums are actually the most underrated.
