If you really need / want a multi-tool then I'd think you're better off with a Gerber than a Swiss Army Knife; I think the screwdriver blade is the only extra one I've actually used on my Swiss Army Knife in twenty years. The pliers on a Gerber are admittedly pretty usable, but really most of the extra bits and pieces on these knives are of dubious utility.
Personally I prefer an Opinel No 8 - cheaper, lighter and much better as a knife than any of the above. Mine also works as a flat blade screwdriver since the very tip was broken off about a decade ago but I wouldn't recommend it for that!
