Short answer: a tie on sound quality. Both are rated 3.6/5 (#703 and #743 of 1291 in-ear headphones) at nearly the same price ($129.99 vs $129), so choose on features and fit.
Why pick the Kinera Celest Phoenixcall: The median of 16 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.38 dB spread. Watch for: A 6.1 dB peak near 1.5 kHz can make cymbals and sibilance sound sharp.
What the Tekkusai Lucid does well: A broadly balanced tuning with a preference score of 69 against the Harman target. Watch for: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Kinera Celest Phoenixcall or the Tekkusai Lucid 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.
