My mother used to make chicken and dumplings from scratch, and they were ten times better than anything I've ever gotten in a can. She also made mac and cheese from scratch, and took it to all the covered dish dinners at church. I think something made from scratch is almost always going to beat processed food every time.
I say almost, because I made the mistake of following a pumpkin pie recipe from scratch. I had no idea how complicated and messy it is to scrape out a roasted pumpkin to make the filling. Real pumpkin can be very stringy, which is why a lot of people prefer to use canned pumpkin in their pie recipes. Live and learn.
