SAT vs ACT what score is better

ok so I’am from Puerto Rico with English as a second language and took the SAT and ACT in the SAT I got 420 R, 540 M, 440 W = 1,400 Composite

In the ACT I got: 20 in English, 23 Math, 19 Reading, 21 Science, 9 Writing(Essay) = 21 Composite

What score is better?? or is there superscore?

Based off of [SAT-ACT</a> Conversion chart](<a href=“http://teachers.sduhsd.k12.ca.us/lccounseling/sat-act_conversion_chart.htm]SAT-ACT”>http://teachers.sduhsd.k12.ca.us/lccounseling/sat-act_conversion_chart.htm) and [Compare</a> ACT and SAT Scores | ACT](<a href=“http://www.act.org/solutions/college-career-readiness/compare-act-sat/]Compare”>http://www.act.org/solutions/college-career-readiness/compare-act-sat/), I would suggest that the 960 CR+M SAT is equivalent to the 20 ACT… I’d send the ACT though imo.
