Is blowing sinus mucous out better than snorting it in?

When I am congested, say from illness, often it is not very easy to blow much of it out my nose. It often seems easier to snort in and have it drain seemingly down my throat into my stomach, where I imagine it being harmlessly (to me) fried by stomach acids.

Some people have at times told me that they think it is best expelled from the body and so blowing the nose they consider far superior, and they consider inward snorting to be counter-productive or a sort of dead-end road.

I’m wondering what others’ opinions or (especially) knowledge on this, er, front, is?
