I've tried both on my 3-screw SBH, and I'd say the reflex style sight affords a better view of your surroundings and proposed target. But man, I always had a hard time finding the dot on the "screen" after the first shot. The tube style red dot forces you to concentrate on that circle, and, for me, made acquiring the dot easier. Eventually, I settled on the Millett tube-type sight that I've used for many years.
