I don't own a TSPROF but looks like a well built, if not overly engineered knife sharpener. I have seen a video from a youtube guy named wrangler star, and he is big fan.
To me the biggest difference is the stykes. They will both get an excellent edge, but the WE does it with 2 stones for each grit and TSProf does it with one. Wicked edge should work faster, but its a personal preference
