I normally shoot in weaver: In the Weaver stance, the body is bladed partly sideways in relation to the target rather than squared towards it. The elbows are flexed and pointed downward. The strong-side arm is slightly straighter than the weak-side arm. The shooter pushes out with the gun hand, while the weak hand pulls back. This produces a push-pull tension which is the chief defining characteristic of the Weaver stance.
But some people like Isosceles: the arms are straight and the gun is positioned directly in front of the shooter. This produces the triangular shape which gives the stance its name.
It depends on how you feel and what you like!
