They are all great. The KitchenAid Artisan stand mixer is perfect for small batch baking, kneading dough, or whipping cream. With a 3.5 peak horsepower motor and 325-watt power rating, it can handle any job you throw at it with ease. The 5-quart bowl has an ergonomic handle for easy lifting so you can move the bowl to the sink and dishwasher without strain. When you need more power and a larger bowl, the KitchenAid Professional 600 stand mixer can handle it. With 5 peak horsepower and a 580-watt power rating, it is the most powerful KitchenAid stand mixer available. The 6-quart bowl's ergonomic handle makes lifting the bowl easily a breeze for even the largest of kitchen tasks. What's great about having both is that you can choose the best one for each job.
