For forearm growth
For forearm growth, reverse wrist curl rates well ahead on our research criteria: more of the work on the forearms, more stretch.
Both are good choices, and they train the forearms differently. Using both across your week covers more of the muscle than either alone: in studies, varied exercises grew parts of a muscle that one exercise missed. (Fonseca et al., 2014; Costa et al., 2021)
The research score comes from these, scored by hand from the studies. Lifter scores appear once an exercise has 10 ratings. How scores work
Reverse Wrist Curl. Targets the wrist extensors, which most pulling barely trains. Only light weights work, so progress is slow.
For climbing, towel hang rates well ahead on our research criteria: more carry-over to climbing.

About the same: both are easy to learn.
Reverse wrist curl needs dumbbells and a bench, so a home gym covers it. Towel hang needs a pull-up bar, so a home gym covers it.
About the same: both rate Excellent for joint and recovery cost in our research rubric.
