Short answer: a tie on sound quality. Both are rated 4.4/5 (#102 and #109 of 450 in-ear headphones) at nearly the same price ($129.99 vs $129), so choose on features and fit.

Why pick the Moondrop Starfield 2: Seven squig.link measurements give the Starfield 2 a preference score of 78.6, with mids and presence all within about 1 dB of target so vocals and instruments sound open and well defined. The tradeoff: Sub-bass falls about 2.5 dB short at 30 Hz, so the deepest rumble is lighter than on bassier sets.
The case for the Queen of Audio Ryusei: Its single dynamic driver earns a preference score of 78.8 and a smooth 1.37 dB spread in the median of 4 squig.link measurements. The catch: Presence drops about 4.1 dB below target, softening vocal edge and snare attack.
Buy the Moondrop Starfield 2 or the Queen of Audio Ryusei on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
Moondrop Starfield 2: $129.99 Amazon eBay
Pros: Seven squig.link measurements give the Starfield 2 a preference score of 78.6, with mids and presence all within about 1 dB of target so vocals and instruments sound open and well defined. Midbass sits 1.7 dB above target for warmth without masking detail. At 15 ohms and 122 dB/Vrms it gets loud from any phone or dongle.
Cons: Sub-bass falls about 2.5 dB short at 30 Hz, so the deepest rumble is lighter than on bassier sets. Air runs 3.9 dB high with a 6.6 dB peak near 8.1 kHz, which can make cymbals and esses sound hot, and the low 15 ohm impedance can let high output impedance sources shift its tuning.

Queen of Audio Ryusei: $129.00 Bloom Audio eBay
Pros: Its single dynamic driver earns a preference score of 78.8 and a smooth 1.37 dB spread in the median of 4 squig.link measurements. Bass rises about 3.3 dB above target between 60 and 200 Hz, giving rich, punchy low end and warmth that suits bassy and warm tastes. Upper mids stay on target, so vocals keep their natural tone.
Cons: Presence drops about 4.1 dB below target, softening vocal edge and snare attack. Treble is uneven, with a 6.5 dB peak near 8.4 kHz that can sharpen sibilance and a 5.5 dB dip near 11 kHz that trims air, and the low mids run 1.3 dB hot, adding some thickness.
