DynastyDaily verdict
Graf is the only player ever to win the Golden Slam in a single calendar year and spent more weeks at #1; Serena edges by 1 Grand Slam title and modern era depth. The DynastyDaily call: Margaret Court (24) still leads the all-time list, but Serena vs Graf is the cleanest open-era #1 conversation — Serena gets the slight nod on raw Slam total.
