Short answer: a tie on sound quality. Both are rated 4.2/5 (#259 and #267 of 1291 in-ear headphones) at nearly the same price ($2,300 vs $2,299), so choose on features and fit.
Why pick the Letshuoer Sonata: A tribrid flagship with isobaric dynamic woofers that measures well (score 77) with a tight 1.54 dB spread from the target. The tradeoff: Very expensive for a score that budget IEMs match, and treble sits about 2.2 dB below target.
What the Shuoer Cadenza 12 does well: A preference score of 76 with deep, well extended bass, only 0.5 dB short of target at 30 Hz from its 10 mm dynamic woofer. Watch for: An 8 dB dip near 5 kHz pulls the presence band 5.5 dB below target, so vocals, snare and guitar attack sound recessed and soft.
Buy the Letshuoer Sonata or the Shuoer Cadenza 12 on features: they are rated the same for sound quality at close to the same price.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
