Short answer: the Kinera Loki Divine Mark. Both are rated 3.9/5 for sound quality (#477 and #532 of 1291 in-ear headphones), and the Kinera Loki Divine Mark costs $3,399 against $5,200 for the Subtonic Storm, so with nothing between them on sound quality, price settles it.
Why pick the Kinera Loki Divine Mark: The median of 3 hobbyist measurements gives it a solid Harman preference score of 73 with a 1.87 dB spread. Watch for: A 10.9 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
The case for the Subtonic Storm: A titanium-shelled tribrid that measures well (score 72 across twelve measurements) with the tightest spread from target of this group (1.85 dB) and full sub-bass. Watch for: Very expensive, and sold in the UK in pounds with no US price.
Buy the Kinera Loki Divine Mark. Both are rated the same for sound quality, and it costs $1,801 less than the Subtonic Storm.

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.
