===== '''Rival comparison'''<ref name=":3" /> =====
The primary competitor engines of the LEAP is the Pratt & Whitney's PW1000G (also known as the PurePower PW1000G) series. The PW1000G engine is part of Pratt & Whitney's geared turbofan (GTF) technology, which aims to improve fuel efficiency, reduce emissions, and lower noise levels. Both the LEAP and PW1000G engines are designed to power the next generation of single-aisle commercial aircraft and are competitors in the market for narrow-body jet engines.

|-
|Propulsive Efficiency
|style="background: green; color: white;" | Larger fan diameter allows higher bypass ratio, leading to improved propulsive efficiency and fuel savings.
|style="background: red; color: white;" | Gear system optimizes fan and LP spool rotation, potentially enhancing propulsive efficiency.
|-
|Thermal Efficiency
|style="background: orange; color: white;" | New generation combustion system and advanced materials increase thermal efficiency. Higher operating temperatures require additional cooling systems and materials.

|-
|Noise Reduction
|style="background: orange; color: white;" | Designed with noise reduction in mind. Centrifugal FOD ejection system helps protect against debris-induced noise.
|style="background: green; color: white;" | Gear system allows for lower fan rotation speeds, contributing to noise reduction.
