to the OP... the benefit is it's cheaper (when comparing like to like). The wider looms make volume production easier, as fewer looms need to be run to produce the same amount of fabric.

Nothing to do with the selvage or lack thereof. That comes down strictly to the materials used. The yarns and the dye.

Leg twist comes from the skewing that happens as the denim's twill weave tightens up during shrinking, not to do with chainstitching. Think of it this way, if you had a totally square piece of raw denim, and shrunk it, it would be left slightly diamond shaped. Or in the case of a pant-leg, the vertical seams shift into a slight spiral.
(in modern production, the raw fabric is often pre-skewed before sewing so that shrinking does not distort the shape)
How that relates to roping is that the fabric is tightly folded twice over itself at the hem. So when this skew happens the fabric bunches up, because the stitching opposes the tendency of the fabric to spiral on itself. This is why it's called 'roping'. It has a distinct spiral effect if you look closely.
(Note: chainstitching is not essential to this, it's more dependent on a narrowish hem, stitched very tightly so that the fabric can't shift to accomodate the spiral)

I'd be ashamed to cuff OE jeans.
not that anyone in real life even knows the difference..
plus OE unravels
OE means "open-ended" and it's the type of yarns (as opposed to ringspun), and has nothing to do with selvage or unraveling.
Jeans can be OE and selvage, or ringspun and non-selvage.
Atelier La Durance are non-selvage. I'm hardly ashamed of the cuff on mine.
Pablo-T put it up there... The actual selvage is more or less meaningless. A great vintage detail, chance to put a signature line, nothing more. The actual quality is dependent on the quality of cotton, the spinning method, the dye used, and the dying technique.
