I've sharpened about a hundred knives on my Wicked Edge system, I find that the knives aren't any sharper than when I started, but rather I am a LOT faster
I got the travel version back in the day as it's very portable, I just use a C-clamp to clamp it down to whatever table I happen to be at. Then I sharpen using 100/200 and then jump to 800/1000 to sharpen. I mostly do work knives (kitchen) so I don't try to put a polish on the blade. Polished blades look great but I find that leaving a few microscopic 'teeth' on the edge gives the best result when cutting things like tomatoes or meat.
I do think their new version of the "Pro" sharpening system looks very cool too:
