Short answer: a tie on sound quality. Both are rated 3.7/5 (#658 and #670 of 1291 in-ear headphones) at nearly the same price ($249.99 vs $249), so choose on features and fit.
Why pick the Moondrop x Crinacle Silicon: A tribrid collaboration with Crinacle, combining a dynamic driver, two balanced armatures and two MEMS drivers. The catch: Sub-bass falls about 3.4 dB short at 30 Hz.
Why pick the QoA x Eir Aoi Misty Blue: A collaboration with singer Eir Aoi, with two dynamic drivers and two balanced armatures. Watch for: Treble sits about 4.4 dB below target, a dark, relaxed balance.
Buy the Moondrop x Crinacle Silicon or the QoA x Eir Aoi Misty Blue 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.
