I cook everything from scratch for my family.
I think as far as usefulness my mini chopper comes in the most handy and I really love this set https://www.amazon.com/gp/product/B07HLMB4YD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I have a mandolin and I have hurt myself (without gloves) and it's honestly a hell of a lot of work.
I have a large cuisinart. I use it sometimes. It's large and it's heavy and it mostly lives in the closet except for once a month when it comes out to make bulk meals. And by this I mean I make 5 dinners for 5-7 people....so 25-30 individual meals. I wouldn't really recommend it for a single person unless you really like things like making pie crust, oat flour or nut butter....in quantities enough for many meals or people.
