Lee joon gi is the male lead of both drama, the similarity isn't obvious but you have a mc who frequently gets himself into trouble by trying to shoulder everything by himself, and female lead who worries/cries about him, and due to misunderstanding, she questions his love.
Both stories are revenge based dramas. Also the male and female leads knew each other when they were younger and also the parent of the female lead is the bad guy..
Although TBDW is about the spies, and All In is about the world of the casinos. Both dramas deal with revenge, change of identity, mafia world, and romance.
Same leading actors, a somewhat similar plot-line - JG is historical while TBD&W is Modern - TBD&W is the better drama in my opinion.
Both shows are about a guy infiltrating an organization for revenge. They both have a very similar atmosphere (Lots of action and spying!) and both of the leads have a similar kind of "forbidden" romance.
They are both excellent dramas, with touching characters and forbidden love. You have the same male lead, and the story il also about someone who's ready to do what it takes to avenge his family. Fate is also a big part of both dramas.
= Same lead actors as the main couple (I personally don’t find their chemistry the best in both dramas but the female lead is more bearable in Time Between Dog and Wolf than Gunman, perhaps because there’s a second more compelling female lead in Gunman).
= The actor who plays the real dad of the female lead in Time Between Dog and Wolf is the same actor who plays the dad of the male lead in Gunman in Joseon
= Father of a woman (female lead in Time Between Dog and Wolf, second lead in Gunman) who has a thing for the male lead is the one who killed one of his parents
= Male lead has two identities in both dramas, one before his supposed disappearances (death) and one after. His second identity is used to spy on the villain for the sake of revenge plus other things he or the organization he belongs to need to accomplish.

In both dramas main lead has to almost turn himself into a monster in order to fight a super scary father-like figure. Both dramas show two brothers and a girl between them. So, very similar revenge stories and love stories, only the setting is different - one is about spies and narcotics and another is about gangsters and casino-hotel business.
