In general, I recommend the SwissTool X and Spirit over the other tools of the same size.
Some of my multitools:
SwissTool X
SwissTool Spirit
SOG PowerLock S60
old Leatherman SuperTool
original Leatherman PST
Leatherman Fuse
Leatherman Juice CS4
Leatherman Crunch
Leatherman Micra
SOG Crosscut
Sears Craftsman slip joint pliers multitool (really a Schrade ST5)
I sold off an original Gerber (palm pincher), a Schrade Tough (to open) tool, and a few others which were unimpressive.
Comments:
I didn't like the current generation of full sized Leatherman tools when I tried them briefly -- perhaps an unfair test.
My SwissTool X and Spirit have the best fit and finish and the tools are easiest to access. Phillips screwdrivers slip too much -- more than my other multitools.
My old Leatherman SuperTool has the best screwdrivers overall. Used and carried this tool daily for many years and it never failed or rusted. Blade lock system is cumbersome and entire tool must be open to access blades. Otherwise, a winner. I prefer it to the newer Leatherman models.
SOG PowerLock has the best pliers, but the other blades are underwhelming. Lacks a good, small screwdriver.
Leatherman Micra has the best scissors. SwissTool X scissors are next best.
