Neutralisation does not depend on pH value and the strength of the acid and base only. The amount of these substances matters too. Even if a strong acid and a strong base are used, there is almost a difference in concentration of H3O+ and OH- ions in solution. According to which substance of those are stronger (referred to their ion concentration), the solution is more acidic or basic.

When [H+] = [OH-] the pH (if T = 298 K) = 7.00, by definition.

It matters not how such a solution were created.

If you are worried that you mentions mol and I converted to conc. then worry not, for the two substances with the same amount are in the same solution and hence must have a common volume.
