Short answer: the Moritz Dragon. It ranks #285 of 1291 in-ear headphones by sound quality, rated 4.2/5, at $555.99. The YU9 Audio Que ranks #344, rated 4.1/5, at $539, $16.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Moritz Dragon: The median of 5 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.62 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The tradeoff: A 6.1 dB peak near 10.9 kHz can make cymbals and sibilance sound sharp.
Why pick the YU9 Audio Que: The median of 22 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.81 dB spread, and its mids sit within about 1.1 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 4.3 dB low with a 6.8 dB dip near 5.6 kHz, so vocals and instruments lose some bite.
Buy the Moritz Dragon. It is rated higher for sound quality, and the $16.99 saving on the YU9 Audio Que is not enough to make up the difference.

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.
