why integrator op-amps are overused than differentiator op-amp in practical circuits or in solving problems?
 

An op-amp is just that, an op-amp. In the real world reducing the upper frequency gain by turning the circuit into an integrator reduces the wideband noise at the output. A differentiator would increase the noise at the output and its function is avoided as far as possible.

another reason is, it does not allow for DC negative feedback in the overall loop
