There is only one thing I find actively improved by the addition of raisins, and it's oatmeal-raisin cookies.

In most other contexts, I'm either I'm mostly to raisins but would prefer them to be some other kind of dried berry, like cranberry or blueberry/bilberry, (this is true of salads and rice dishes, as well as scones/bagels), or would definitely prefer them not to be there at all (e.g. muesli).

I'm more benevolently disposed towards golden sultanas, but maybe because they tend to pop up less in contexts where I would prefer to avoid raisins.
