Short answer: a tie on sound quality. Both are rated 3.9/5 (#538 and #535 of 1291 in-ear headphones) at nearly the same price ($29.99 vs $29.90), so choose on features and fit.
The case for the CCZ CZ10 TianGong: A broadly balanced tuning with a preference score of 72 against the Harman target. Watch for: An uneven response, 2.0 dB standard deviation from target.
Why pick the Tripowin x 0diBi Vivace: A very cheap single dynamic IEM tuned with 0diBi. The catch: A 1.88 dB spread from the target still leaves some peaks and dips.
Buy the CCZ CZ10 TianGong or the Tripowin x 0diBi Vivace on features: they are rated the same for sound quality at close to the same price.

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.
