Short answer: the Moondrop Variations. Both are rated 4.4/5 for sound quality (#128 and #137 of 1291 in-ear headphones), and the Moondrop Variations costs $599 against $629 for the TANGZU TianPeng, and with sound quality even, the cheaper one is the better buy.
The case for the Moondrop Variations: In oratory1990’s measurement it scores 79 for preference with a smooth 1.46 dB deviation. The tradeoff: Presence and treble each sit 1.7 dB under target and a 4.4 dB dip near 9.8 kHz takes some bite off cymbals, giving it a dark, warm balance.
The case for the TANGZU TianPeng: Squig.link measurements from six hobbyists give the TianPeng a preference score of 79.1 with a tidy 1.43 dB deviation, so its eight driver hybrid of dynamic, balanced armature and bone conduction units hangs together coherently. The tradeoff: A 4.5 dB dip near 4.1 kHz and a presence band 2.3 dB below target take some bite out of vocals and guitars, which can sound slightly veiled.
Buy the Moondrop Variations. Both are rated the same for sound quality, and it costs $30 less than the TANGZU TianPeng.

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.
