Short answer: the Hisenior Mega5EST 7th Anniversary Edition. Both are rated 4.0/5 for sound quality (#394 and #458 of 1291 in-ear headphones), and the Hisenior Mega5EST 7th Anniversary Edition costs $549 against $599 for the Night Oblivion Butastur, so with nothing between them on sound quality, price settles it.
Why pick the Hisenior Mega5EST 7th Anniversary Edition: The median of 4 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.73 dB spread. Watch for: Presence sits about 4.3 dB low with a 5.5 dB dip near 5.1 kHz, so vocals and instruments lose some bite.
Why pick the Night Oblivion Butastur: A broadly balanced tuning with a preference score of 73 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
