Does HCl or h2so4 have a lower pH?

When HCl dissolve in water, it will dissociate into one mole of H+ ion and Cl- ions. Whereas, the H2SO4 dissociate into two mole of 2H+ and SO4^2- . … Thus, decrease in the H+ concentration mean lower the PH value, which greatly reduce H2SO4 ‘s strength than HCL.
