what features you want on your tool are up to you but i would suggest leatherman over any of the competition.
i have held them all in my hands and the leathermans just feel much more solid.i have given many leathermans hell with no problems whatsoever.leatherman pioneered the multi-tool industry and has the best warranty and customer service,not to mention the largest selection of tools.
they may cost more but are the busse of multi-tools while the other ones are the SOGs and gerbers of multi-tools literally.
my thoughts.
