It's hypothetical. Don't over-think it. Still, both people would be handicapped in different respects. How many vegans can climb trees and identify the various edible species of plant life on an island. I'll tell you one thing, the idea of having to live off plants in the wild scares me. Unless you happen to come upon something like an apple, orange, fig or other recognizable tree you are screwed. The guy in the Survivorman show makes it look easy, but he has an army of consultants preparing him before each trip. That's how he knows that a specific grass is edible and that the root of a given plant is good food. Without that most city dwellers would not know what to do with most vegetation on an island. You could easily kill yourself if you eat the wrong plant. In that sense meat is easy. So long as the animal doesn't kill you first and you clean and cook it you are generally pretty safe. An omnivore can eat anything, ants, grubs, bugs of all kinds, worms, snakes, lizards, crabs, rabbits, rats, etc. You just have to be smart enough to make a trap and a fire. Find a reasonably flat rock, heat it up and use it to cook. I think most people who have watched a little television can figure out how to do that, particularly when coupled with the intense need to survive. Making fire isn't easy. I've done it. I failed miserably a bunch of times before I got it. My hands were shredded, but I did it. If you are not injured and persevere it isn't impossible. It can be painfully hard, but not impossible.
