H1+H4+H4EAD-- PP or Not?

My wife EAD expires on AUg 1st.I am in illinois.
My employer is applying for my H1,H4 and H4 EAD next week all together. I am thinking to apply in PP but i have seen some cases where EAD is also getting approved along with H when upgraded to PP after the biometrics appointment.

Any inputs on which one is better.
