Short answer: a tie on sound quality. Both are rated 4.4/5 (#93 and #106 of 450 in-ear headphones) at nearly the same price ($399.99 vs $399), so choose on features and fit.
What the Moondrop Blessing does well: A preference score of 79 in oratory1990’s measurement, with the midrange from 200 Hz to 3 kHz held within 0.3 dB of target, so voices and instruments sound natural and correctly weighted. The tradeoff: Sub-bass runs 3.5 dB below target from 20 to 60 Hz, so deep electronic and hip hop bass hits a bit lighter than it should.
Why pick the Unique Melody 3DT: Four hobbyist measurements on squig.link give the 3DT a preference score of 79.0, with its three dynamic drivers producing a balanced response where every band from 60 Hz to 10 kHz sits within 1.6 dB of target. The catch: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing.
Buy the Moondrop Blessing or the Unique Melody 3DT on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
Moondrop Blessing: $399.99 Apos Audio eBay
Pros: A preference score of 79 in oratory1990’s measurement, with the midrange from 200 Hz to 3 kHz held within 0.3 dB of target, so voices and instruments sound natural and correctly weighted. The hybrid layout of one dynamic driver and four balanced armatures keeps the response even, at 1.68 dB standard deviation. It suits listeners after a neutral or gently warm sound, and it rates above the cheaper Tanchjim Oxygen.
Cons: Sub-bass runs 3.5 dB below target from 20 to 60 Hz, so deep electronic and hip hop bass hits a bit lighter than it should. A 5.3 dB dip near 11.4 kHz trims the airy sparkle on cymbals. The Etymotic EVO shares the same rating for less money.

Unique Melody 3DT: $399.00 Linsoul eBay
Pros: Four hobbyist measurements on squig.link give the 3DT a preference score of 79.0, with its three dynamic drivers producing a balanced response where every band from 60 Hz to 10 kHz sits within 1.6 dB of target. Midbass is gently lifted for warmth, and presence stays near neutral, so vocals sound clear and natural. At 113 dB sensitivity it runs easily from a phone.
Cons: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing. Sub-bass sits about 1.4 dB below target at 30 Hz, and it costs more than the equally rated Binary 1900 and Etymotic EVO.
