For biceps growth

Dumbbell Curl vs Preacher Curl

For biceps growth, the two are close. Preacher curl rates slightly higher: more stretch.

Dumbbell curl is easier on the joints.

Both are good choices that train the biceps the same way, so they swap freely. Rotating between them every few weeks is an easy way to vary your training.
