Generics vs brand names

To save money, I've been trying generics lately. For my three favorites, here's what I've discovered:

Cheerios - generic is not good. This is the worst of the three I've tried. Tastes highly processed and not very oaty. Cardboardish.

Corn flakes - generic is significantly worse than Kelloggs, but it's edible. Just less malt and corn flavor, but otherwise okay.

Life - surprisingly, because I assumed this was the most complicated of the three, the generic is almost as good as the brand name. A small enough difference that I pick it up when I see it (since it's nearly half the price). The drawback is that it's more rare than the other two - only a few stores nearby even have a generic Life.

How do other generics match up against the brand names?
