For glute growth
For glute growth, the two are close. Reverse lunge rates slightly higher: more stretch.
Hip abduction machine is easier to progress.
Both are good choices, and they train the glutes 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
Hip Abduction Machine. Works the side of the glutes (gluteus medius and minimus). Easy to load, with a small stretch.
Reverse Lunge. Stepping back keeps the front shin upright and stretches the front glute. Balance makes heavy loading harder.

About the same: both are easy to learn.
Hip abduction machine needs a machine, so for most people it’s a gym exercise. Reverse lunge needs dumbbells, so a home gym covers it.
Hip abduction machine: it rates Excellent for joint and recovery cost in our research rubric, against Strong for reverse lunge.
