For instance, if an opponent isn't shoving as wide as NE would dictate, you are gaining EV from the extra blinds you get. But, if you don't stray from NE and call based on NE, he will be gaining EV on your calls.

Which effect is stronger?

By definition, in a Nash Equilibrium no player can increase his own EV by changing his strategy (if all other players stick to the Nash Strategy).

So, to answer your question: The second effect must not be stronger (otherwise we don't have a real NE). [The effects could theoretically cancel each other out and the strategy-change may be EV-neutral. But for NLHE-HU Push/Fold a deviation from the NE is typically -EV if your opponent plays Nash.]
