There isn't a difference. If one does exist then it is only a psychological manifestation of stereotypes. For instance someone who chases/observes a storm three times or less during a year could be a better chaser than someone who chases/observes storms more than three times a year. It's just how people are.
Over a period of time, you're exactly wrong. Skill requires exposure. Going out three times a year over a period of 10 years VS someone else going out 15-20 times a year over the same period is no contest, if both the individuals are dedicated. There's no substitute for experience, regardless of how philosophical you wanna wax it.
