Ruiz/Rubio bring the higher ceiling and should control most rallies through heavier bandejas and better net occupation, especially in Silver-level tempo. Windahl/Vasquez can absolutely compete if they speed up transitions and win the first-volley battle, but they’ll likely need a high break-conversion day. Slight edge to Ruiz/Rubio in two tight sets if they manage lobs and avoid over-forcing from mid-court.
