i have an old 4.5 qt KA, a 5qt KA Artisan, and a 7qt Cuisinart. I love the 1000wt motor of the Cuisinart…i have to doubt that it is going to be a work horse. My 5qtArtisan is a newer one (glass bowl) and it overheats and loses speeds over 6, BUT i love the way it makes to-the-top-of-the-bowl buttercream recipes. The Cuisinart just doesn’t get the same result as the stirring action of the KA. Even when mixing cake batter, I have to scrape the beater of the Cuisinart because there are air pockets of dry on it, while the KA doesn’t have that issue. That’s a bit annoying, but at least i know it isn’t going to quit. And the Cuisinart has a much better warranty. I would be really interested in the 7qt KA, but considering how shoddy their new construction is, i’m going to wait to see how they review.
