Short answer: a tie on sound quality. Both are rated 4.1/5 (#345 and #315 of 1291 in-ear headphones) at nearly the same price ($53.19 vs $49.99), so choose on features and fit.
Why pick the KZ ZS10 Pro X: The median of 10 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.86 dB spread, and its mids sit within about 0.9 dB of target, so vocals and instruments sound natural. The catch: A 6.4 dB peak near 10.6 kHz can make cymbals and sibilance sound sharp.
Why pick the Moondrop Pudding: The median of 16 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.50 dB spread. The tradeoff: Presence sits about 3.8 dB low with a 5.5 dB dip near 2.3 kHz, so vocals and instruments lose some bite.
Buy the KZ ZS10 Pro X or the Moondrop Pudding 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.
