I wouldn't offer an opinion on which is the "best" sharpening system, mostly because I don't own a Sharpmaker, but I will say that I am very satisfied with the Lanksy system. I have watched videos of the Sharpmaker and can see how it might perform better in some instances, such as the aforementioned recurve blades, and I may well invest in one for just that reason someday. Depending on the OP's demands on his blades, and his ability to set up the Lansky system consistently from session to session, it will perform at least as well as the Sharpmaker in the vast majority of applications for, IIRC, about half the price. If you're recurve-heavy in your collection though, you may want to spring for the extra ducketts.
Very light recurves are not a problem on the Lansky though.
Also, just thought about this, if you plan to sharpen a lot of large camp/survival/chopper knives, go straight to the Spyderco. The Lansky is about useless for them without doing the blade in two or three sections, moving the clamp and trying to limit the stroke to only overlap just right, which is nigh impossible. I don't use the Lansky on my choppers at all, and one of them is a Kershaw Outcast with a big, sweeping recurve to boot.
I've had the Lansky for several years and have used it very little. Not because it doesn't work, but because it doesn't work well on the knives of mine that are hardest to sharpen, like the choppers. I'm fairly handy with a whet stone, crock sticks and a strop though, so I only break out the Lansky when I have to reprofile, or remove a small chip in a blade. It's pretty much a waste of time and energy to get it all set up just to dress up a slightly dull blade. The Spyderco would be more like the crock sticks in that regard, and therefore, might get a lot more use than the Lansky.
Good Lord, I've confused myself here. No doubt I have been no help to the OP! Sorry about that. Good luck with your choice! LOL
