Short answer: the QoA Bijou. Both are rated 4.1/5 for sound quality (#380 and #325 of 1291 in-ear headphones), and the QoA Bijou costs $111.46 against $119 for the Ucotech RE-3 Pro, with sound quality a draw, the lower price decides it.
Why pick the QoA Bijou: A broadly balanced tuning with a preference score of 74 against the Harman target. The catch: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
The case for the Ucotech RE-3 Pro: The median of 3 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.72 dB spread. Watch for: A 5.4 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the QoA Bijou. Both are rated the same for sound quality, and it costs $7.54 less than the Ucotech RE-3 Pro.

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.
