I have shot both of these broadheads, and personally, I like the Rage better due to its construction and the operation of the broadhead itself. I have seen the spitfires not open completely on impact because they open from the tip. If the broadhead enters from an angle, then the blades will not fully deploy 100%. The rage opens from the rear using what they call a slip-cam system, allowing the blades to fully open as the broadhead impacts. You can check out the website; ragebroadheads.com.
