Are Good Mornings Good Substitutes for Back Extensions?

Wondering if they are similar exercises or completely different.

They have some differences, but yes.

I like back raises/ekstensions better. But they’re a good substitute yes.

I like them both.
Also look at SLDL , semi stright ,not rigid knee. Straight leg deadlift.
GMs give some upper back work.
