Introduction:-
Some people are only using ng-show instead of ng-hide="!true" Or some peoples are using ng-hide instead of ng-show="!true". Technically we don't need ng-hide directive. But! I know angular introduced ng-hide for  standard coding structure. And please understand me, I am asking about the performance not difference. 
My Question:-
So my question is what about the performance of this following scenarios?
- ng-hide="true"vs.- ng-show ="!true"
- ng-show="true"vs.- ng-hide="!true";
