"best of it" is quite rare situation in short game. More often you both will have vulnerable hands. So the winner will be the one who takes the most with worst of it.
And there is always optimal frequency spewing/taking pot uncontested, depending on your opponent. Against a fish you should never spew, against thinking TAG/LAG you MUST spew to be unpredictable or to force opponent to be tooo tight/passive/predictable.

Predictability lets your opponent to make easy folds and easy bluffs (like if you cap PF only with JJ+,AK - it's quite easy to release a hand postflop for your opponent). You should always try to keep you opponent uncertain and predictable so he will start to make mistakes you're waiting for (like calling down too much with thin value or never bluffing, raising only with best of it - it's quite common mistakes against smart LAGs ).
