You use circulars the same way you would dpns. I prefer magic loop for sock cuffs. Here is a video. She is knitting all the stitches. But you can do ribbing, etc. The technique is mostly to split the stitches in half on each needle. And work one set at a time then slide the stitches & work the other side. You can also do both socks at once.
It has been a long time since I knitted anything exclusively on dpns. I don't know if the ladders wash out. Maybe it depends on the yarn.
