I also use both types of binding. Right now I am doing a Grandma's Flower Garden (doubleknit) and I am using bias binding.
As far as fraying on the fold...both straight and bias will probably wear the same on the fold.
I don't press a fold into my binding, straight or bias. I match up the raw edges, stitch that down to the quilt, then turn the binding as I stitch, adjusting the biding as I go...works great & no fold line to hint that I didn't get the binding on oh so straight..looks perfect because of the no fold line also.

I have read or heard that bias binding wears longer, and that straight grain binding frays at the fold quickly. So I use bias most of the time, except for wall hangings that will get no wear. For baby quilts I always make 100% cotton bias binding, because usually they get washed so much.
Has anyone else heard about, or had experience with differences in wear in bias versus straight binding? Straight is soooo much easier.
