Another boring super question

Hi all. Question. I am M 38. Wife is F 36. I work full time earning $130k pa. Wife is full time SAHM. My super balance is $280k. Wifes is $120k. Does it make any sense for me to pay $100 a week into her account to keep it ticking. Or Am I better off just adding that to my isn account knowing that it’s all “our” money anyway. Thanks
