I prefer wigwams but that's just because I grow my beans in large tubs. I'm sure I read somewhere recently though that wigwams are more stable than traditional rows but I suppose it depends on your set up & how many beans you are growing. A lot of people use 'inverted ' wigwams or canes (narrow at the bottom /wide at the top) as well so that the beans apparently hang on the outside & are easier to pick.
