D-ring Trousers

I am considering some D-Ring trousers (flannels/cotton)--but have never tried them. Is there any consensous among people who do/have worn them. I personally don't like belts (they pinch my stomach), and love braces. Of course I am restricted w/braces because of their rarity in dress these days. So are D-ring trousers worth a try--or is there not much advantage over belts?
