Define "stronger"
If they are solutions in water then, in one sense, they are as strong as eachother because a mixture of equal volumes of each will be (nearly) neutral.

Dredging my chemistry memory: For a solution of these vicious chemicals in water:

• pH 14 (strongly alkaline, eg 1M sodium hydroxide) would have an OH^- concentration of about 10⁰, and H⁺ concentration of 10^-14
• pH 7 (neutral, like water) would have an H⁺ = OH^- concentration=10^-7
• pH 1 (strongly acidic, eg 0.1M hydrochloric acid) would have an H⁺ concentration of about 10^-1, and OH^- concentration of about 10^-13
• To match the "strength" of the pH 14 solution, you would need a pH 0 solution (eg 1M HCl).
• To neutralise a quantity of 1M NaOH (pH 14), you would need an equal quantity of a 1M HCl solution (pH 0) or 10 times the quantity of 0.1M HCl (pH 1).

Oops!
It seems I lost track of the zeros.
Well spotted.
