Short answer: a tie on sound quality. Both are rated 4.0/5 (#96 and #110 of 481 over-ear headphones) at nearly the same price ($199.99 vs $199), so choose on features and fit.
What the Beyerdynamic DT 990 Pro does well: A preference score of 82 comes from a lively, bass-forward tuning, with bass from 60 to 200 Hz about 2.4 dB above target for punch and drive. Watch for: Treble runs about 5 dB above target and air above 10 kHz is nearly 9 dB hot, with a peak near 10.9 dB at 11.9 kHz, so cymbals and sibilance can sound harsh, especially at high volume.
What the HIFIMAN Deva Pro does well: A preference score of 81 with a deviation of 2.2 dB in oratory1990’s measurement shows a smooth, slightly warm response with the midrange close to target. Watch for: Sub-bass is about 7.5 dB under target, so deep bass lacks rumble.
Buy the Beyerdynamic DT 990 Pro or the HIFIMAN Deva Pro on features: they are rated the same for sound quality at close to the same price.

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.
