Lima beans are called butter beans this end. They can be a bit dry and grainy, but I was brought up on them and I like them. They're good to mush up into some kind of dip or to spread on bruschetta, mixed with other stuff such as olive oil, rosemary and chilli flakes. If I'm using canned beans I tend to stick with cannellini or borlotti. Or chick peas if I think the recipe can take the substitution. Or all three.
