Strong bases produce less [H3O+] than weak bases?

Do strong bases produce less [H3O+] than weak bases? Or is it the opposite? I thought that strong bases produce more OH-, meaning there's less [H3O+]. Can someone confirm/deny?

I would think that the stronger the base, the lower [H3O+]. pH is the measure of [H3O+] and the higher the pH the stronger the base. So I don't think produce is necessarily the right word, but looking at concentration.

Strong bases completely dissociate into conjugate acids and OH-. This means that the initial concentration of the strong base will be the amount of OH- in the solution. If a weak base and a strong base of equal concentrations were mixed with water, the weak base would produce less OH-, as it does not completely dissociate. Either way, the dissociation of the weak base into its conjugate acid and OH- lowers the pH; however, it does not directly impact the H3O+ in the solution and does not produce H3O+.
