It would be like Gattaca.
Us "God-children" would be discriminated on in favor of those that have been genetically modified prior to birth.
If I could have children that won't be prone to things that affect my family like migraines, psoriasis, diabetes, high blood pressure, obesity, Parkinson's, any cancer, poor vision, etc., I'd do it. I'd add height in there, too, because poor things, especially the males, if they're as short as me.
Oh, and nose. I have my mother's nose shape, but my father's tip. His nose can die with him. No one needs that thing.
I'd just pass on my mother's nose that is in my genes.
