Short answer: the qdc SUPERIOR. It ranks #541 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $99; the KiiBoom Allure ranks #610, rated 3.8/5, and costs $99.99, so there is little reason to consider the other one.
Why pick the qdc SUPERIOR: A broadly balanced tuning with a preference score of 72 against the Harman target. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the KiiBoom Allure does well: A broadly balanced tuning with a preference score of 71 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the qdc SUPERIOR. It is rated higher for sound quality than the KiiBoom Allure and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
