Short answer: the Creative Aurvana Ace 2. It ranks #936 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $90.72; the Harmonic Empire GuoJia ranks #1000, rated 3.2/5, and costs $119, so there is little reason to consider the other one.
The case for the Creative Aurvana Ace 2: True wireless earbuds with ANC, IPX5 water resistance and an unusually wide codec list, including aptX Lossless, aptX Adaptive, AAC and LC3, so they get the best connection from most Android phones. The catch: Squig.link hobbyist measurements put its preference score at 65, with bass and low mids running about 2 dB thick while an 8.9 dB peak near 7.9 kHz makes cymbals and sibilance sharp and splashy.
Why pick the Harmonic Empire GuoJia: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: Treble about 6 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Creative Aurvana Ace 2. It is rated higher for sound quality than the Harmonic Empire GuoJia 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.
Measurement data: the Creative Aurvana Ace 2 from aden, dhrme, kazi, listener, obodio, regancipher, therollo9 and vsg; the Harmonic Empire GuoJia from audioamigo, bassaudio and csi-zone, all via squig.link.
