Short answer: a tie on sound quality. Both are rated 3.3/5 (#962 and #939 of 1369 in-ear headphones) at nearly the same price ($80 vs $79), so choose on features and fit.
What the Snowy Axis does well: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the Tangzu Li Zhi: A broadly balanced tuning with a preference score of 65 against the Harman target. The tradeoff: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Snowy Axis or the Tangzu Li Zhi 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.
Measurement data: the Snowy Axis from boizoff, iemocean and scboy; the Tangzu Li Zhi from bassaudio, csi-zone, dl, soundcheck39 and soundignity, all via squig.link.
