Should I apply Early Decision or Regular Decision

I am starting my senior year of high school and looking to apply to Syracuse University. My gpa is a 3.9 and my sat is 1160, nothing special to solidify an admission to that school. Freshman and Sophomore year I did not take many honors, but Junior year I took all honors and same with Senior year with the inclusion of 1 ap class. I was wondering if I should apply early decision to increase my chances at getting admitted. Or is it more worth it to apply regular decision so they can take into account my honors and ap courses senior year to show upward mobility? And if I apply early decision, will they even see what I am taking senior year?

What college would you be applying to with Syracuse? Can you take the SAT again in October?
