Submitting SAT vs. ACT

I’ve heard various explanations concerning whether or not colleges favor SAT over the ACT. Some are claiming that colleges now look at both equally, but looking at the stats, most students still turn in the SAT.
My superscore for SAT (taken twice) is 2180 (M:800, CR: 680, W: 700), with individual composites of 2170 both times. My score for ACT (taken once) is 35 (M: 35, W: 35, R: 34, S: 36).
Based on these scores, I would really like to only turn in my ACT… but will this hurt my chances? Do colleges prefer having both SAT and ACT scores over only having ACT scores? I also took two subject tests (Math II: 800, Chem: 760)…
Yikes! I just wanna know if colleges secretly want to see both.

Your ACT score is significantly better than your SAT score.
And I would also submit your SAT Subject tests.

Yeah, I was definitely going to submit my SAT II’s and ACT.
I’m just not sure if colleges would look at my application unfavorably if I didn’t turn in an SAT score along with them.

No they won’t. Only send the SATs to those schools that require all scores to be sent.

Send only the ACT. You have a great score! Congratulations.

Your application will NOT be viewed in a negative light.

Submit the SAT I only if it is required.

And submit your SAT II tests.

The one thing I have always wondered about ACT to SAT comparisons is that I feel that because the ACT is required to be taken by all high school students in some states that a lot of people score low on the test compared to the SAT. For example a 29 on the ACT puts one at around the same percentile as someone who scores 1960 on the SAT. The problem I see with this is that because more underachieving students take the ACT that scoring in the 90th percentile is not as big of an accomplishment as scoring in the 90th percentile on the SAT.

Some states require the SAT to graduate. Idaho is one.
