Short answer: the AME Gaia. Both are rated 3.8/5 for sound quality (#620 and #550 of 1291 in-ear headphones), and the AME Gaia costs $3,200 against $3,499 for the Canpur CP622B, so with nothing between them on sound quality, price settles it.
The case for the AME Gaia: A broadly balanced tuning with a preference score of 71 against the Harman target. Watch for: An uneven response, 2.1 dB standard deviation from target.
Why pick the Canpur CP622B: The median of 13 hobbyist measurements gives it a solid Harman preference score of 72 with a 1.92 dB spread. Watch for: Presence sits about 5.2 dB low with a 7.5 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
Buy the AME Gaia. Both are rated the same for sound quality, and it costs $299 less than the Canpur CP622B.

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.
