I had a cafe and then a guest house, fifteen years plus, and used a Magimix for all those years. It started to crack, and I needed to replace, so my son's partner and my husband persuaded me to buy a Kenwood processor, but I wish I had bought another Magimix. It was so much easier to use. Single speed because it regulated itself depending on the consistency of the ingredients. I used it for making cakes for the cafe on my day off, as well as pizza bases, soup, biscuits, tomato sauce for homebaked beans, bases for croustades, etc.
The Knewood I have cannot be put in the dishwasher, whereas the Moulinex could. It also had a smaller container to grind nuts, spices and coffee. It was quite expensive, but worth it. Not as expensive as Kitchen Aid, though.
