WebEdge-trailing is "safer" to sharpening and to stones and/or knives. You run the risk of gouging soft stones with edge-leading. Edge-leading is "faster" to sharpening. The swiping motion (YMMV) for me is the most consistent. It aids sharpening to greater degree when you are sharpening. Always use edge-trailing strokes when you are stropping.
