Short answer: a tie on sound quality. Both are rated 4.1/5 (#356 and #375 of 1291 in-ear headphones) at nearly the same price ($34.99 vs $38), so choose on features and fit.
What the KZ Vader Balanced does well: The Balanced factory tuning of the triple dynamic KZ Vader, very cheap at about $35, with about 1.5 dB more bass than target and four tuning switches (score 75). The catch: It rates below the KZ Vader, which has less bass, and the same listing sells both tunings, so check which one you order.
The case for the SGOR Luna: The median of 8 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.09 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The tradeoff: A 9.2 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
Buy the KZ Vader Balanced or the SGOR Luna 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.
