DCM or CCM Flyback Converter for Battery Charging

Hi. I would like to design a flyback converter that will be used for charging three batteries. I couldnt decide whether to choose CCM or DCM. I looked up some books but they say different things about them. I chose FPS IC that includes internal mosfet. I have all necessary equations about converter but i need to decide DCM or CCM. Output power will be 3 x (13.6V x 0.7A) = 28.56W. 0.7A is charging current for a battery. Multiplied by 3 due to three batteries. Parallel charging will be used. Also i can implement quasi resonant. Which one is best for battery charging ?
