Short answer: a tie on sound quality. Both are rated 4.4/5 (#112 and #98 of 450 in-ear headphones) at nearly the same price ($34.99 vs $34.99), so choose on features and fit.
What the Ooopusx OP22 does well: Twelve hobbyist measurements on squig.link give the OP22 a preference score of 78.9, and every band from 60 Hz to 16 kHz sits within about 1.3 dB of target. Watch for: Sub-bass falls about 2.3 dB short at 30 Hz, so deep synth bass has less rumble than the bassier KBEAR KB02.
Buy the KZ Vader or the Ooopusx OP22 on features: they are rated the same for sound quality at close to the same price.

Ooopusx OP22: $34.99 Amazon eBay
Pros: Twelve hobbyist measurements on squig.link give the OP22 a preference score of 78.9, and every band from 60 Hz to 16 kHz sits within about 1.3 dB of target. That makes it one of the tamer budget hybrids, with treble that never jumps more than 3.8 dB and no harsh spikes. Its 124 dB SPL/V sensitivity means a phone drives it to loud levels easily.
Cons: Sub-bass falls about 2.3 dB short at 30 Hz, so deep synth bass has less rumble than the bassier KBEAR KB02. A 3.5 dB dip near 10.2 kHz trims some sparkle and air from cymbals, and slightly thick low mids can make vocals sound a touch dull.
