SAT score vs ACT Score

SAT 1380 (690 both), essay 6/7/6

ACT 31

English-34
Math-29
Reading-33
Science 26

Which of these scores would technically be seen as better? To me, it looks right now that these are about the same (because 1380 translates to 30-32 on the charts).

A 31 ACT is equivalent to a 1420-1440 so that would technically be better.
