My understanding is all the current B747-400F operators went for the extra payload instead of the extra range. For example, Singapore Airlines' B747-400F service between SIN-LAX (as well as to other US cities) does make two stops (TPE/SEL and ANC). IIRC, SQ has fifth-freedom rights between TPE/SEL and the US only on selected flights.
