I have always held the opinion that an in-swinging corner gives the attacking side a better advantage. Simply because the ball is travelling in the direction of the goal and therefore the attacking players will also be moving toward the goal.
An out-swinging corner gives momentum to the defending team as the ball is travelling away from the goal and puts them on the front foot when looking to clear it.
