Should I keep on using two facebook ad accounts to sell on same fb page and same website?

[Qamar_Aftab]

I am using two ad accounts on facebook. I am on shopify Plus. One ad account is for shoelace the other one is for the ads that I create myself. I wonder if it is better to use just one ad account for everything so that ads from both my accounts do not compete with each other. Need help deciding what to do.
