I believe that most of us use double-fold binding, so that adds a lot of fabric on the edges. A simple hem, or a single folded binding may get thin and fray much faster if the quilt actually gets used and washed.
On mine, I usually machine sew the binding on the front and hand-stitch it down with tiny stitches on the back. A few, I machine sew the binding to the back, pull it to the front and use a fancy machine stitch to secure it down. Fast and fun.
