I bake and cook lot as a hobby. I have both kitchenaid and kenwood chef (two diff properties). Kitchenaid is just fine for day to day life, someone mentioned paint coming off the hook- mine are stainless steel versions which can go into the dishwasher. The attachments are good.
I'm unsure what your other option is or the needs are? Cook and bake a lot? Perhaps a kenwood chef would be your better option?
Having both, I prefer the kenwood chef marginally. I prefer the attachment nose? of the kitchenaid because they are more simple which means it hasn't broken. The kenwood has had a lot of use with the attachments and one is loose. I probably could send for repair but life, I just hold it in place - but if I don't hold it, it doesn't work!
Hooks I prefer Ken, they're the heavy stainless steel (there are diff ones available, mine are bulky type dough hook is a triangle type hook at the bottom? Smooth?
Balloon whisk and regular beater both are good.
Creamer I prefer Ken, but not mad about kitch.
Pasta shape maker def kitch is superior. (Not pasta roller!!!)
Mince and sausage thing but metal version def kitch
Slicer/blender def Ken and got kenwood xl hand blender would also recommend the workhorse.
Grater type things I prefer Ken but kitch is okay.
Kenwood is better when lifting and dropping but more of a btch to clean if you have spillage (rare). It just feels more sturdy.
Some people have mentioned cheaper options - possibly? I had a cheaper option in kitchenaid property and it was frustrating when I was going there and trying to bake.
Oh and unmixed layer at the bottom - depends what you're mixing. Most the of the time even with the Ken or kitch I do need to still get the spatula once to get it mixed through. Heavier batters etc I made pancakes with kitchenaid for the kids and I have to get the spatula a handful of times when adding the milk - but same goes for kenwood. Most batters you have to at least 1x to be sure in both mixers!
Oh kitch came with two bowls - one fits into the other.
Ken only came with 1x and had to get a couple extra because we do bake a lot.
I dislike hand washing when I'm baking and cooking, usually time constraint so I got the extra bowls.
