Short answer: a tie on sound quality. Both are rated 4.7/5 (#26 and #30 of 450 in-ear headphones) at nearly the same price ($22.99 vs $21.99), so choose on features and fit.
The case for the Aoshida E20: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. The catch: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings.
The case for the KZ Gale: Squig.link measurements, the median of six hobbyist samples, give it a preference score of 82, solid for a very inexpensive single dynamic in-ear. The catch: Sub-bass sits about 1.8 dB under target, so deep electronic bass has less rumble than bassier rivals.
Buy the Aoshida E20 or the KZ Gale on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
Aoshida E20: $22.99 Amazon eBay
Pros: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. Sub-bass sits within a decibel of target down to 30 Hz, and the mids stay within about 1 dB, so vocals sound natural with solid bass underneath. Its dual dynamic driver design and budget price make it a sensible pick for warm or mildly V shaped tastes.
Cons: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings. Bass from 60 to 200 Hz runs about 1 dB lean, so it has less punch than bass focused alternatives. It is rated level with similarly priced rivals such as the KZ EDZ and DDHiFi Janus 3 rather than above them.

KZ Gale: $21.99 Amazon eBay
Pros: Squig.link measurements, the median of six hobbyist samples, give it a preference score of 82, solid for a very inexpensive single dynamic in-ear. Bass and lower midrange sit close to target with a slight upper bass lift, giving a warm, relaxed tone. Sensitivity of 107 dB/mW at 24 ohms means a phone drives it easily. It shares its rating with the KZ EDZ and DDHiFi Janus 3 at a similar price.
Cons: Sub-bass sits about 1.8 dB under target, so deep electronic bass has less rumble than bassier rivals. The presence band runs nearly 2 dB low with a 2.8 dB dip near 3.5 kHz, pushing vocals slightly back, and its 1.35 dB average deviation is less even than the best in-ears.
