Short answer: a tie on sound quality. Both are rated 3.6/5 (#738 and #770 of 1291 in-ear headphones) at nearly the same price ($19.99 vs $20.99), so choose on features and fit.
Why pick the SGOR Venus: A very cheap single dynamic IEM with treble right on the Harman target and full sub-bass to 20 Hz, scoring 69 across seven measurements. The tradeoff: A 2.42 dB spread from the target shows peaks and dips that better tuned sets avoid.
The case for the TRN MT4: A very cheap 10mm dynamic IEM that measures close to the Harman target, with full sub-bass to 20 Hz (score 68 across six measurements). The tradeoff: A 2.27 dB spread from the target still leaves some peaks and dips.
Buy the SGOR Venus or the TRN MT4 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.
