I was a charter member (out of 9) of National Math Honor Society and I helped create our Chapter’s Constitution and was elected Vice President for that year, and President the following year.
Is this better or worse than being the founder of like the chess or computer science club?
There is no objective “better” or “worse”. It depends entirely on your responsibilities in each position, your time commitment, what you accomplished, and how it “contextualizes”, so to speak: how it relates to the rest of your application.
If you’re trying to decide which to list first on applications, don’t worry. If you’re trying to pick one or the other, decide which has more meaning to you, and reflects who you are and what you want to become. You weren’t “just a charter member” you were an officer both years. Depending how active the honor society was, and how active you were in managing those activities, that may be more impressive than starting a club.
Neither is a red carpet path to the admissions office. Both are nice on the resume.
Students (and their parents) need to eliminate the words “impressive,” “better,” “best,” or similar words from their vocabulary until after college admissions decisions are made. It is the rare application/course schedule/EC that will “impress” admissions. Perhaps the AO that read Malala’s application was “impressed,” but she set the bar high.
