For hamstring growth
For hamstring growth, the two are close. Good morning rates slightly higher: easier to progress, more stretch.
Nordic curl keeps more of the work on the hamstrings.
Both are good choices, and they train the hamstrings 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
