They are completely different stones so your going to notice a lot. The shaptons will cut faster, polish higher and have much greater feedback. Your going to need a good lapping plate too, the XC DMT is not going to cut it. A good nagura or small diamond slurry plate will be needed for the higher grit stones, they tend to load and in some cases using the stone with a slurry is helpful.
Top of the line stones that produce great edges, you will not be disappointed.
