What type of flaps is the more effective?

Statements are made for the aerodynamic efficiency of a wing with a slotted flap, depending on the slot size Influence of Single Slotted Flap

A Clmax of was achieved with the 30% single-slotted Fowler flap designed flap slot geometry for various flap settings are shown in Figures 7
