Short answer: a tie on sound quality. Both are rated 4.3/5 (#233 and #232 of 1291 in-ear headphones) at nearly the same price ($249 vs $249), so choose on features and fit.
Why pick the Beats Powerbeats Pro 2: A preference score of 77 in hobbyist measurements on squig.link, with a smooth 1.8 dB standard deviation and every band from 20 Hz to 10 kHz within about 2 dB of target, gives a balanced and natural sound. Watch for: Treble above 10 kHz runs about 8 dB below target, with a 13.6 dB dip near 11.2 kHz, so cymbals and room ambience lose their airy shimmer.
What the DUNU PRS6 does well: The median of 3 hobbyist measurements gives it a very good Harman preference score of 77 with a 1.78 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 3.7 dB low with a 6.2 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
Buy the Beats Powerbeats Pro 2 or the DUNU PRS6 on features: they are rated the same for sound quality at close to the same price.
