Vegetable Cutting Machine Is A Food Processor Really That Helpful?

Is a food processor really that helpful? - vegetable cutting machine

I would like to cook, but I will not have much time to the preparation work, like chopping vegetables. So I decided to buy a Cuisinart 14-Cup-robot mostly on the fact that the package, so you can put the vegetables into the whole machine without pre-cut in the cascade fit. I know that everything depends on the recipe, but I am wondering whether the food processor, in general, which is much time to prepare the meal for me to reduce it. Would it be better, a Vidalia Chop Wizard? Are probably not in the food processor for many others when cutting things. Thank you.
