All sin is founded on rebellion to God. Therefore, in that sense, all sin is equivalent. But as far as how sinful behavior and actions manifest themselves, all sins are not equal nor do they have the same effect on the sinner or those around him or her.
It’s a long topic and I don’t have time to do it justice, but just as all physical ailments are not the same (hangnail, sunburn, measles, AIDs, cancer...), similarly the spiritual sickness of sin is a continuum.
I often wonder about the morality of Christian musicians. I know some of them have been faithfully married for years, and some have adopted children. Most seem to me like fine people. Anyway, my judgment is meaningless. That of God is all that matters.
