Coyota1 brought out an important point when he referred to exit pupil. What scope will work best has something to do with your age. As we age the pupils of our eyes dilate less in low light. While one person may be able to use the extra light of a 50mm scope, another may not. For some 40mm may be all they can use. If you can't use the extra light, you are better off with a smaller scope. The only way to find out is to try out some friend's scopes at dusk and compare them. Optical quality is of course important in the equation.
