Single sitting vs slightly higher superscore

So I recently got my scores back from my second SAT, and I improved from a 2120 to a 2260. Huzzah! However, it raises a question - 2260 is the superscore (790 CR, 680 M, 790 W, if it matters) whereas single sitting it’s a 2250 (670 M instead).

Assuming I’m applying to a school that doesn’t require you submit all tests, is it better to only submit one score, or submit two with a slightly higher superscore? Are single-sittings looked upon favorably? Will 10 points make any kind of difference? Should I stop thinking about the SAT on a freaking Saturday night and do something fun instead?

It shouldn’t make too much of a difference but I think you should send both scores in! That’s what I did and I was in a similar situation (2180 single-sitting vs 2220 superscore). It really can’t hurt you imo.
