Short answer: the Softears Karma. Both are rated 4.2/5 for sound quality (#284 and #299 of 1291 in-ear headphones), and the Softears Karma costs $2,599 against $2,999 for the Final Audio A10000, with sound quality a draw, the lower price decides it.
What the Final Audio A10000 does well: Bass, low mids and presence all sit within about 1 dB of target on the squig.link measurements, so the low end is full depth but uninflated and voices come through with natural tone. The catch: A sharp 10.4 dB peak at 8.1 kHz lifts the 6 to 10 kHz band 4.8 dB over target, which can make cymbals, sibilants and hi hats sting at higher volume.
What the Softears Karma does well: The median of 6 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.80 dB spread, and its mids sit within about 1.4 dB of target, so vocals and instruments sound natural. Watch for: Its 1.80 dB spread is less even than the best measured sets.
Buy the Softears Karma. Both are rated the same for sound quality, and it costs $400 less than the Final Audio A10000.
