Short answer: a tie on sound quality. Both are rated 3.5/5 (#835 and #778 of 1291 in-ear headphones) at nearly the same price ($899 vs $899), so choose on features and fit.
The case for the Campfire Audio Supermoon: A 14mm planar magnetic IEM with full sub-bass to 20 Hz and a 67 Harman score across three measurements. The tradeoff: Expensive for its rating, and a low 94 dB sensitivity needs more volume.
Why pick the Symphonium Audio Triton: The hybrid of one dynamic driver and two balanced armatures keeps the bass and midrange close to target, with the bass band within 0.5 dB and the upper mids within 0.9 dB in squig.link measurements. Watch for: Across hobbyist measurements the presence band sits 5.1 dB low with a 6.6 dB dip near 6.3 kHz, which dulls vocal edge, cymbals and fine detail.
Buy the Campfire Audio Supermoon or the Symphonium Audio Triton 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.
