Short answer: a tie on sound quality. Both are rated 4.0/5 (#438 and #402 of 1291 in-ear headphones) at nearly the same price ($249 vs $249.99), so choose on features and fit.
What the HUAWEI FreeBuds Pro 4 does well: A broadly balanced tuning with a preference score of 74 against the Harman target. Watch for: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
The case for the Tanchjim Origin: The median of 27 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.07 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The tradeoff: Sub-bass is 4.1 dB short at 30 Hz, so deep bass lacks rumble.
Buy the HUAWEI FreeBuds Pro 4 or the Tanchjim Origin 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.
