I spent several years as a vegetarian, and then a few as a vegan, and I wouldn't/won't touch any of those products, either. I've tried them, and they're gross. They don't taste like or feel like meat.

There are enough delicious vegetarian and vegan recipes that it makes very little sense to go vegetarian and then eat processed imitation meat. I found being vegan significantly easier when I just looked for recipes that happened to be vegan.
