Should I submit my ACT score or the SAT with subject tests?

Hello, I have scored a 1530 (750 English, 780 math, all sevens writing) on the SAT, a 35 (35 English, 34 Math, 36 Reading, 36 Science, and 32 Writing) on the ACT, a 760 on the Mathematics Level 2 subject test, and a 770 on the literature subject tests. As of now, my ED school would be Williams College, which has a testing policy of SAT with 2 subject tests or the ACT. I want to make my application as competitive as possible and was wondering if I should submit my SAT, ACT, or both. Thank you in advance for any assistance.
