H2SO4 and HCl are both strong acid...however...do note that H2SO4 is a diprotic acid while HCl is monoprotic...in other words...one mole of H2SO4 will ionise in water to give 2 moles of H+ ions while one mole of HCl will only give you 1 mole of H+ ions...the concentration of H+ ions will determine the acidity of the solution...in fa ct...phosphoric acid, H3PO4 is even more acidic than H2SO4.
