Easier than what? String beans are just picked as is. Podded beans - those harvested for the bean inside for dry storage and the pod pitched - are relatively easy to harvest if allowed to dry on the vine. That includes soy and garbanzo, lima, black-eyed butterbeans, etc.. The dried pods can just be placed in a brown paper bag or an old pillow case or any kind of sack and threshed then the beans removed.

But if you want to harvest them for fresh eating rather than dry storage then most any variety will need you to break open the pods by hand or invest in a bean/pea sheller.
