Duke Tougou - otherwise known as Golgo 13; he's loved by the ladies, hated by his enemies, is enamored with firepower, and can take out a target from several kilometers away. With an arsenal of weapons at his command, Golgo 13 is hired by a variety of people to take down hijackers and more - but he also must protect himself against those who want to take down the legend himself!
Ryo Saeba and Kaori Makumura are private detectives who make up the City Hunter team -- problem solvers who can be hired by writing 'xyz' in a certain train station. Ryo's uncanny accuracy with a gun is surpassed only by his lecherous tendencies, while Kaori provides the sideline support -- usually in the form of a 50,000 kg mallet to keep Ryo's ecchiness under control!
Both City Hunter and Golgo 13 feature protagonists who are the best at what they do, expert marksmen and tacticians, who take on a job and always see it through to the end. Both protagonists also share a love of women though City Hunter is unable to control his lusts. Both series are episodic in nature though Golgo 13 is much more serious, but if you liked one try out the other.
Both of the stories aren't that same and the characters dont share much similarities. But Duke and Ryo do share the same skill in being a great marksmen. If you are looking for another anime with epic shoot skills Golgo 13 or City hunter are just right. If i was to compare Ryo to Duke in terms of skill i would say they are pretty much on the same level.

Badasses don't have to talk much, do they? They just have to kill things and be badass while doing it. Gungrave is basically a violent mob story with admittedly quite a bit more action and animation then Golgo 13, but if you like guys with guns in gritty environments killing stuff... Gungrave does that all and manages to be pretty fun, too. Check it out.
Both series are about men who don't need to talk much. Their actions speak very loud when they murder anyone they are hired to or people that simply get in their way. Golgo 13 is mainly episodic murder of the week stories where Gungrave has a clear plot through and through but you'll enjoy watching these manly men kick some serious butt.
Taichi Keaton, a former British special forces operative, now works as an insurance investigator for the world-renowned insurance agency Lloyd's; but his true passion is history and archaeology, which he fulfills by teaching at universities and visiting various ruins. Make no mistake though, there is far more to Mr. Keaton's job than simply filing insurance forms and writing reports! His investigations take him around the world and into situations ranging from run-ins with the Russian mafia to solving murders and even foiling terrorist plots. There's never a dull moment, much to Keaton's dismay!
This is an unusual recommendation, but bear with me.
If you liked episodes of Golgo 13 where the protagonist gets embroiled in an issue of fine wine culture, excellent musicians, and the episodes grounded a little more on semi-plausible terrorist and gang related issues, it's possible you might like Master Keaton.
When it comes down to it Master Keaton employs a similar formula: An incredibly skilled and dexterous Japanese man arrives somewhere in the world, finds some sort of problem, and arrives at an ingenious solution. The problems Keaton faces tend to be a little more flexible then 'kill something' and the series lacks the stone cold machismo and hypermasculinity that is the epitome of Golgo 13 - although Master Keaton is a former SAS agent and a skilled survivalist, he has a friendly, self-affacing style that makes people understimate him, rather then Golgo 13's capacity to stand out like a sore thumb in any situation.
Nevertheless, if you enjoyed this series meandering episodic seinen components, it's possible you may like Master Keaton.
Granted Golgo 13 mostly bored me to tears and Master Keaton got me a little tired in places too, so take this recommendation with a handy grain of salt.
These 2 shows are worlds apart plot wise but both would appeal to the seinen fans. Keaton is slow paced and about a detective. Golgo 13 is simply about a man that is an assassin. They are both however are episodic and the lead characters are very strong willed that will do anything to get their jobs done. Just try one if you liked the other.
A giant wall looms over Tokyo, shielding the city from a dangerous otherworld called the 'Hell's Gate'. Within the city, things are no less terrifying because Contractors, psychopathic killers with phenomenal powers, have started to appear. These killers are compelled to pay a price every time they use their powers, often in the form of a meaningless or painful task. As their deadly habits rack up a gruesome death toll, Kirihara Misaki and her team from the Foreign Affairs Public Security struggle to solve the cases and bring the Contractors under control. Their task is further confounded by the interference of a masked individual they title Messier Code BK201, a man with abilities that allow him to fight and defeat the Contractors. Who is this BK201? How can the Contractors be stopped permanently? And what does the appearance of the Hell's Gate mean for the people of Tokyo?
In the world of politics, public officials are abusing their power and using the citizens' hard earned money for their own whims - be it extortion, payoffs, or worse. To combat this problem, the Japanese government created their own version of the FBI: an independent agency with tremendous resources, the Government Crime Investigation Agency! Jotaro Zaizen, GCIA agent, is a manly man who uses a variety of manly means to take down the corrupt and the unjust. With his super-legal privilege Zainers Gold Black card and his trademark saying "da bomb," Jotaro will do whatever it takes to both get the job done and win the ladies.
While Zaizen Jotaro is remarkably more campy than Golgo 13, both have one important thing in common: they each star a manly man who does manly things. Women, power, aiding or assisting crime - these guys do or have it all.
