Short answer: a tie on sound quality. Both are rated 4.2/5 (#283 and #261 of 1291 in-ear headphones) at nearly the same price ($22.80 vs $22.99), so choose on features and fit.
What the TANGZU Wan’er S.G 2 does well: The median of 9 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.83 dB spread, and its mids sit within about 1 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 3.4 dB low with a 5 dB dip near 6.1 kHz, so vocals and instruments lose some bite.
The case for the TForce Yuanli: The median of 7 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.78 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The tradeoff: Treble sits about 3.5 dB low, so it sounds a little dark.
Buy the TANGZU Wan’er S.G 2 or the TForce Yuanli 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.
