As stated above, it really depends on where you are using it and what you want it for.
A Victorinox will tackle most everyday chores without much problem, they are also great to pair up with a bigger knife if you are going in the outdoors (especially for the saw). They're elegant, relatively lightweight and way easier to sharpen and mantain than other multitools, beside there are lots of models to choose from according to your needs. It is well known that the saw and can opener on any Victorinox work way better than those on a Leatherman.
However, if you work in construction, or ride a motorcycle or a mountain bike, or even if your car has the habit of breaking down in the middle of nowhere, the pliers will really come in handy (pliers can also be used for light hammering, digging, grappling, etc.)
A lot of people say that if you really need pliers, you are better of carrying a pair of professional grade pliers in your toolbox, however with a Leatherman, your pliers are always around when you need them and you don't have to carry a tool box.
So again, it's really up to you, if you think you can do without the pliers, then Victorinox is the way to go, if not, definitely consider a Leatherman.
