Short implant vs. Sinus Lift?

63 y/o female patient wants implant to replace missing tooth #14. CBCT shows low bone height, but enough to place a 6mm implant. Pictures show the planning with a 4.8 x 6mm Dentsply Astra EV implant. Question is would you place the short implant or do a crestal sinus lift?
