The above points are all valid and helpful. Shooting next to a braked rifle is annoying, which is why I will try to set up at a station with vacancies to either side at least. If the range is full up I will not shoot braked, unless the neighbors are as well. If I am shooting braked not many people will set up next to me though...whether this is a plus depends on the types of shooters that frequent your range. At the one I frequent (public) this can definitely be a plus...we get all kinds.

Another point is that a break can change your POI, mine shifts up a couple inches and a tad left at 100 with the brake. Something to consider.
