Sometimes the amount of cushion will aid against nics depending on your skin type. I'm not prone to nics and rarely get them but I still prefer lather that provides cushion above slickness. It feels like the razor isn't touching your skin and to me feels protective. I liken cushion and slickness to grease. If you poured water on concrete then rubbed your hand across it you will still feel the coarseness of the concrete . If you poured grease on the concrete your hand may not ever touch the concrete as you rubbed against it. it would have a "layer" between your hand and the ground. And it would glide (if it also had slickness in the case of lather).
