Why doesn't the suction power behind a fan feel as strong as the wind coming out of the front?

Because it's diffuse. The air coming out of the fan is in a very narrow path - the fan's energy is pointing in one direction. The air going into the fan might be coming from anywhere behind it, not from any particular angle, so the moving air is harder to feel at any one spot.
