Two categories, not two competitors
Feature counts mislead here. My Music Staff is a lesson platform: its records are students, lessons and tuition, and it handles all three well. Music Shop Suite is a back-office system: its records are physical units, contracts and money across sales, rentals, repairs and lessons.
So the deciding question is not which has more checkmarks. It is whether you run a teaching studio that owns a few instruments, or an instrument business that also teaches. Owners answer that in a second, and the answer predicts the right tool better than any table.
