If my serger is threaded with a neutral thread when I finish quilting, I will use it before binding. I use my serger for finishing seams on garments all the time. I'm comfortable with using it and can just trim the ravels off the edges as I stitch. I like the way the serged edge behaves while I apply the binding. I don't need to pin as much.
Serging might be more advantageous on pieced borders/edges where you have lots of seams coming up to the edge. I also think it could be an additional way to secure the quilting stitches at the edge.
