D flip flop is the basic flop. It can be used as memories (which is used in many applications). It can also be used as dividers by just adding a not gate. Moreover other flops are not easy to use/modify as D flip flop
D-FF will take less power consumption than any other flops.
T-FF is designed from D-FF with combo logic.
JF-FF is having 2 inputs to toggle. It will be difficult to design as well as controlling the switching activity ..
and more advantages. Please read John knight Digitial slides from Carleton University..
Design a circuit with d ff is easy and also in case of jk ff we required to handle 2 input which is difficult as weel as controlling of both input is also not easy in case of large design.
As sam said D ff also take less power.
