Short answer: a tie on sound quality. Both are rated 4.4/5 (#120 and #100 of 450 in-ear headphones) at nearly the same price ($49.99 vs $53.99), so choose on features and fit.
Why pick the TRN Medusa: Thirteen hobbyist measurements on squig.link put the Medusa at a preference score of 78.7, with a single 12mm dynamic driver that holds bass almost exactly on target down to 30 Hz. The tradeoff: The air band runs about 6.5 dB above target and peaks 8.6 dB near 11.9 kHz, so it can sound hissy and fatiguing with bright mixes or at high volume.
Buy the TANGZU Wan’er SG Studio Edition or the TRN Medusa on features: they are rated the same for sound quality at close to the same price.

TRN Medusa: $53.99 Amazon eBay
Pros: Thirteen hobbyist measurements on squig.link put the Medusa at a preference score of 78.7, with a single 12mm dynamic driver that holds bass almost exactly on target down to 30 Hz. Midbass sits 1.7 dB above target for punchy drums, while vocals in the 1 to 3 kHz range come through clearly. It weighs 5.1 g per earbud and its 30 ohm, 108 dB load is easy for any phone.
Cons: The air band runs about 6.5 dB above target and peaks 8.6 dB near 11.9 kHz, so it can sound hissy and fatiguing with bright mixes or at high volume. It costs a little more than the equally rated KBEAR KB02 and CCA Pianist.
