You can search in the board.

If Iam not wrong there were many questions on advantages of PMOS as input for diff amp. That will a basic idea.

First,Overall dc gain is largely unaffected by the choice since both designs have both NMOS and PMOS drivers.
Secand,For a given power dissipation(bias current),having a PMOS input-pair maximizes the slew rate since PMOS will have larger Veff
Third,Flicker noise is less ofr PMOS
and Input voltage range requirements.
