AP US Hist or MUN

Been doing Model United Nations for 2 years in my high school which is combined with my history class. I’m thinking about doing AP US History next year instead seeing as how its a more rigorous course. Would it look bad that I dropped out of MUN? Would it be better to do it all 4 years? Which course looks better?

I personally would take APUSH. I honestly think you are safe either way though. It might be interesting to take a new history class/topic, but I can understand the hesitation since you could be involved with something for 4 years, which shows commitment.
