All sighting systems have advantages and disadvantages. Iron - sturdy, never runs out of batteries, no reticle to break, but for some of us, they get fuzzy. Scope - add weight to rifle, don't take kindly to being dropped, almost as fast as iron if user mounts rifle to shoulder with both eyes open. Reddot - smaller and lighter than scope, unlimited eye relief, main disadvantage seems to be the batteries. What do you prefer, what uses, and for the poll, if you had to go grab something NOW, what would it have on top of it.
