I have only had experience with the Gerbers, Leatherman Pulse, Wave and Supertool/ST200. The Gerbers pinched my palm when I was trying to use the pliers on a small item whereas the Leathermen have a large gap between the plier handles when the jaws are in the closed position. Also, with about 10 minutes practice, you can open the Leatherman models with one hand. I just takes a little longer to open than the Gerbers since you have to swing the handles out and usually use your thigh. I liked the screwdrivers on Leatherman better since they seem to have sharper corners.
I have no experience with the SwissTool, but anything from Victorinox should be great. I do have significant experience with the Leatherman and the Gerber though and Hands Down, the Leatherman is the better of the two. Much more user friendly and better built.
