You get three Golden Gun shots. You get more than twice as many hammers. I think it's only fair that you survive a hammer if they choose not to use the Super-Killing perk in their perk tree. And Nova Bomb/Fist of Havoc are nukes. You won't be getting Cry Havoc or Space Magic medals every time you use it. FYI, Sun Charge counters those too if you hit them as they start.
