Generation & platform
The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?
Same generation
The Campfire Audio Astrolith - Dual Planar IEM is 11 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price. For 11 years between them, that is a thin return - treat this as a restyle rather than a new platform.
