I didn’t even know about the 7 quart. I have a 6 quart Kitchen Aid, same one for almost 12 years. It’s been dragged to and from places I needed to bake and moved across country 3 times now. It still works great I love it. My want to get a 5 quart Kitchen Aid cause sometimes the bigger ones don’t mix smaller batches as well. Wish I could give you a opinion on Cuisinart but only had the KA. I loved the KA customer service too, I called them when I got my KA (almost 12 yrs ago) and told them it was really loud so it must be broken, I was use to the 5 quart. They shipped me a new one right away…and mine wasn’t broken the 6 quart is lound, has a much bigger motor.
