I avoid hand work like the plague. That said - I like the way the binding looks when hand stitched to the back and I can't for the life of me get my bindings to look good when I try to machine sew it on both sides. It never matches and I have a "ghost" stitch hanging around the outer edge of the binding. So I suffer through hand binding.
I know Sharon Shamber does her bindings all by machine (front and back) and gee ... she wins big shows (and bucks) with her quilts so if its good enough for her (and the judges), then why not? Of course when she does her binding by machine it looks fantastic. Mine looks like an afterthought.
