Well............
I am an unreserved processor cook!
My processors slice far more consistently than I can. My 12 cup processor kneads bread dough wonderfully, without oxidation. People here who know bread like the breads I make in the processor. In fact, an older lady from church had given up on homemade bread, because of her hands, and after having some of my cheddar bread, bought a Cuisinart Classic 11, and is very happy with it.
My carrot cake, which I have posted here several times, is made entirely in the processor, in one bowl. Batter goes together in seconds. (Super Searchalator).
The 5 cup processor is great for smaller batches, and has the wonderful KitchenAid solo disc... one side for slicing, one side for shredding.
I could, and have done without my K45 mixer, and would give up most of my other countertop appliances, but not my proceessors. I might even give up my beloved Radarange over my processors.
I have used a Sunbeam Le Chef, and I agree that it is/was the equal of the Cuisinart. I have used other processors, and firmly believe that no processor is better than most belt drive processors, like the early Farberware and the early Hamilton Beach/Sears.
I dislike preshredded cheese, and with a processor's shredding disc, it's moments to have just the amount of shredded cheese you need. Bread crumbs? Instantly! Grated Parmesan? Poke the button! Grated Parmesan keeps well in a sealed jar in the refrigerator....and tastes worlds better than that nasty stuff in the green shaker can!
I am intrigued by the Breville processor, recently rated best by CR, and also by the Magimix, but I am very satisfied with the machines I have.
I suggest Jean Anderson's Process This! (most recent,) or her New Processor Cooking. (from the 1980s.)
