It depends. I would say that if going all in on Tenacity only gets you to 132%, there is little to gain in doing so on that toon.

Keep in mind, some toons are predominantly used in squads where the lead or a unique boosts tenacity. For example, B1 gives bonus tenacity based on his DB stacks. So a B2 at 132% Tenacity would be much more effective.
