Short answer: the Simgot EM10. It ranks #196 of 1291 in-ear headphones by sound quality, rated 4.3/5, at $499.99; the ARTPICAL Lucifer ranks #359, rated 4.1/5, and costs $500, so there is little reason to consider the other one.
What the Simgot EM10 does well: The median of 19 hobbyist measurements gives it a very good Harman preference score of 78 with a 1.38 dB spread, and its mids sit within about 0.8 dB of target, so vocals and instruments sound natural. The tradeoff: Its 1.38 dB spread is less even than the best measured sets.
The case for the ARTPICAL Lucifer: A broadly balanced tuning with a preference score of 75 against the Harman target. The catch: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
Buy the Simgot EM10. It is rated higher for sound quality than the ARTPICAL Lucifer and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
