Short answer: a tie on sound quality. Both are rated 3.2/5 (#994 and #996 of 1369 in-ear headphones) at nearly the same price ($50 vs $49.90), so choose on features and fit.
The case for the Kotori Audio Zephyr: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Meaoes Eagle does well: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The tradeoff: Treble about 4 dB above target from 3 to 10 kHz, which can sound sharp or tiring at higher volume.
Buy the Kotori Audio Zephyr or the Meaoes Eagle on features: they are rated the same for sound quality at close to the same price.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
Measurement data: the Kotori Audio Zephyr from elrics, obodio, tonedeafmonk and treblewellxtended; the Meaoes Eagle from audioamigo, bassyalexander and mmagtech, all via squig.link.
