It is just another "intermediate result" in a race that could last for 20 years or maybe more (and we are just at the beginning): but now that the PW1100G-JM scored another two sales (TransAsia for six aicraft plus six options and GoAir for 72 aircraft), the Geared Turbo Fan is in the lead over the LEAP-1A again. The LEAP engine scored big during the Paris Air Show, taking the lead by a wide margin then after announcing a design change with a seventh LPT stage and a larger fan diameter. With these changes CFM claimed to be as good if not better than the GTF in fuel burn. That claim was dismissed by John Leahy last week when he said that the GTF would be about 1.5% better in fuel burn.
The GTF has now announced orders for 488 aircraft, the LEAP-1A has announced orders for 465 aircraft.
UPADTE: CFM just annouced that ALAFCO choose the LEAP-1A for the 35 additional A320neo orders. So LEAP-1A is in the lead again:
