Flat boosts are great in events such as :

The World Tournament - only one leader

Ultimate Clash - where you might not be using an optimal sub leader

Category bonuses - Say you are filling in a category where you don't have the best leaders so the boost is low, the guys with the flat boosts can help you clear the even t faster and also keep your bonus levels high. The exact reason I use the LR Androids for bonus rates.
