they're not in the same league, but the swisstool has more tools, and has some that doesn't exist on the 91mm models, like the chisel, sharpened wire scraper.
and it's heavier, if I needed to use one of my tools like a prybar, I'd take my Swisstool's big screwdriver, the rivets look like they're sturdier, as they seem to be in stainless steel while the 91mm's are made of brass.
the cybertool is for medium (and small) tasks, the swisstool is for heavy duty. I almost always wear both on me.
the Swisstool's pliers are superior for heavy duty work, but if you don't need to put real strengh and need precision, the small ones are easier to operate quickly, partly thanks to the spring which gets them back open once you release your squeeze.
