Which Officer Position would be best to hold? Senior Class Officer or National Honor Society Officer ?

I have recently found out that we aren't allowed to hold position in both Offices at my high school. I am currently running for Senior class treasurer, and plan to, if i don't when the election, to run for a officer position in National Honors Society. I've chose to run for senior class officer because i've held that position for the last year and want to continue with it. What i would like to know is which in ur opinion would be the more beneficial position in the terms of what colleges would find more appealing , and which would enable me to be the most productive.
