Why it wins

Each arm works independently, so a dumbbell exposes and then closes a left-right strength gap that a barbell would hide.

Also

Range of motion is wider too — on chest and shoulder work the wrist and shoulder can follow their natural path.

The catch

The trade-off is stabilisation: the same movement takes less weight with dumbbells than with a bar.
