Does it really matter when to buy a dividend stock?

I buy SCHD at the same time every 1st of the month. The next dividend is expected on/around December 8th. Should I still just buy it on the 1st and get the dividend, or wait until after the dividend since the price will drop by the amount of the dividend? It probably is a distinction without a difference I guess. Just curious if there is any actual reason to choose one over the other.
