I use my KA mixer for doughs as the dough hook works so well. I do not use my Magimix FP for beating egg whites as I feel I have less control and not as much air to get into it. I love the FP for all the grating so I avoid accidents as I tend to cut myself on graters, and I use it for particular cakes and cupcakes. I tend to alternate a bit between the FP and the mixer when it comes to cake making.
