Short answer: a tie on sound quality. Both are rated 3.8/5 (#616 and #564 of 1291 in-ear headphones) at nearly the same price ($15.99 vs $18), so choose on features and fit.
The case for the ND Nice: A broadly balanced tuning with a preference score of 71 against the Harman target. The catch: An uneven response, 2.4 dB standard deviation from target.
The case for the TANGZU Wan’er S.G: Crinacle’s measurement gives it a preference score of 71, and squig.link measurements show bass and midrange within about 1 dB of target from 20 Hz to 3 kHz, so voices and instruments sound natural at a very low price. Watch for: Across 25 hobbyist measurements presence and treble sit about 3.5 to 4 dB below target from 3 to 10 kHz, with a 7 dB dip near 6.3 kHz, so cymbals and fine detail sound a bit softened.
Buy the ND Nice or the TANGZU Wan’er S.G 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.
