sharpmaker , I just sold mine, i had the diamond stones and ultrafine stones all the tools to get a razor sharp edge, I have the lansky and hate it so i bought the sharpmaker, I can get a hair whittling edge off the sharpmaker effortlessly , as long as the edge is not chipped, but after i thought i "mastered" the sharpmaker i bought an edge pro and it truly is an awesome piece of sharpening equipment, as far as the lansky i threw it in my junk closet and havent seen it in over a year. I broke my yellow ultra fine stone for the lanksy on purpose just to get the stone out of it, it's great for a car sharpener or for quick free handed touch ups. I'd say sharpmaker or if you want the best of the best go wicked edge or edge pro. the Wicked edge and edge pro are a tad bit pricey though but to me the edges i get are worth every penny.
