CO is 36/29 over 15 hands and has called a 3bet out of position with Q8s

I prefer to play 3bet or fold from SB, and QJs seems like a hand that I should 3bet.

Flop: I don't have any of the sets.I can rep overpairs (AA-JJ) and overcards/flush draws. Villain could have 88 or 66, overpairs (JJ-99), overcards/flush draws and maybe T9s.

Against the CO 3bet calling range that I give to villain, I have about 24% equity. His half pot bet gives about 24% odds to call. Villain does have somewhat aggro stats, although this is over a rather small sample size. Given this knowledge, would this have been a better call? Mathematically, it seems I should have called, and with villain's stats, I'm thinking this is even more true.
