Short answer: the Moondrop Quark 2. It ranks #45 of 450 in-ear headphones by sound quality, rated 4.6/5, at $19.99; the KZ Krila ranks #80, rated 4.5/5, and costs $20.99, so there is little reason to consider the other one.
Why pick the Moondrop Quark 2: For a very low price, the Quark 2 scores 82 for preference in the median of seven hobbyist measurements on squig.link, with a near zero tilt and only about 1.3 dB of unevenness. The catch: Treble is consistently subdued, sitting 2 to 3 dB below target from 3 to 16 kHz with a 6 dB dip near 11.2 kHz, so cymbals lack sparkle and the sound can feel slightly veiled.
Why pick the KZ Krila: For a budget hybrid it measures remarkably well, with a preference score of 79.6 and a 1.65 dB spread in the median of 8 squig.link measurements. Watch for: Sub-bass sits about 1.9 dB under target below 60 Hz, so the deepest rumble in electronic and film scores is a little restrained.
Buy the Moondrop Quark 2. It is rated higher for sound quality than the KZ Krila and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
Moondrop Quark 2: $19.99 Amazon eBay
Pros: For a very low price, the Quark 2 scores 82 for preference in the median of seven hobbyist measurements on squig.link, with a near zero tilt and only about 1.3 dB of unevenness. Bass and midrange stay within about 1 dB of target and the upper response has no peak above half a dB, so it never sounds shouty or sharp. A built in microphone makes it handy for calls.
Cons: Treble is consistently subdued, sitting 2 to 3 dB below target from 3 to 16 kHz with a 6 dB dip near 11.2 kHz, so cymbals lack sparkle and the sound can feel slightly veiled. Sub-bass is about 1.6 dB shy of target, and several rivals such as the KZ EDZ earn the same rating at a similar price.

KZ Krila: $20.99 Amazon eBay
Pros: For a budget hybrid it measures remarkably well, with a preference score of 79.6 and a 1.65 dB spread in the median of 8 squig.link measurements. Bass, low mids and upper mids all sit within 0.5 dB of target, so vocals and instruments come across natural and balanced. A 3.5 dB lift in the air band adds airy detail on top.
Cons: Sub-bass sits about 1.9 dB under target below 60 Hz, so the deepest rumble in electronic and film scores is a little restrained. A 5.3 dB dip near 6 kHz followed by a 6.4 dB peak near 11.9 kHz makes the treble uneven, softening some consonants while adding a touch of glare high up.
