Bee, my experience is similar to Benjamin's. In wilderness situations the component I've used second in frequency to the knife blade is the saw. IMHO, for shelter building, if you can't cut it well with the saw it's too big to waste your energy on anyway. In urban situations, pliars.
To me your choice of multitool or Vic model entirely depends on the above and your comfort with the tool.

Don't buy any more knives or multitools. You are right on the verge of an addiction. Get help! Don't listen to us here.. we're out of control. Find a gearfreak recovery group and join.
