The satiety index measures how full you feel after eating 240 calories of food and how long after eating you feel full again, while the sugar crash scale or glycemic index measures how quickly you get a sugar high from the food and then crash (a low glycemic index is preferable, meaning the food sustains you longer.)
Looking at the chart, the foods at the top right corner are those with the greater satiety and lower glycemic index: More filling and less crashing!
