Both series features a MANLY protagonist who are placed in various scenarios from assassination, adventure & espionage. Cobra is set in Star Wars-like world while Golgo 13 is placed in a realistic urban setting.

These animes are made by men for men as they're full of action, guns, fights, women & overall MANLY! 

Both are awesome shows made to be in an old style on purpose yet both still have great animation they also both feature Manly protagonists and hot chicks in them  

Famous Protagonists with particular personalities with bounties on their heads. Featuring Guns, Awesome Storyline and a lot more. Cobra's Storyline is much darker in sense of more violence, Naked women but in terms of an good action and storyline they're both good.
