Both are romantic comedies set in a workplace with a young heroine in her 20s trying to make it in the publishing business and struggling to find love.

Both suspenseful crime thrillers feature a male detective and female police officer working for a special unit that involves her supernatural ability that can help predict or prevent crime.

Both are feel-good workplace dramas featuring a rookie who not only learns the ropes but brings change to their team as they find their way and develop relationships. They also give insight into the business ( as only J-dramas can do!) in a fascinating way, and have memorable characters who have meaningful arcs.

Both involve forensics and medical students who come to value what they learn from a veteran who wants to teach them the importance of autopsy in determining the truth behind deaths that otherwise would not be revealed.

Both feature a conman character teaming up with a government worker to catch bad guys through unorthodox means.

Both are procedurals involving forensic doctors, and Satomi Ishihara stars in both (although in Unnatural she plays a doctor and in Bull Doctor she plays a detective).

Both dramas involve the newsroom, and issues of truth/fact and government suppression of a free press. Both feature strong protagonists who are veteran reporters with uncompromising ideas about media ethics, and while they are considered to have 'bad' personalities, are trusted anchors.

While Argon's characters work in journalism and Stranger in a prosecutor's office, both feature a protagonist with a unique personality and leadership style (the latter being complained about by all). Both look at corruption that affects real lives, but I felt a similarity more in terms of the writing style and quality directing. Each episode is tightly plotted, with virtually no wasteful scenes.

Both are about broadcast journalism and its many-layered difficulties, and feature the lives of a team as they work and grow together.

Both are about ex-journalists who become tabloid reporters and take on dangerous and controversial stories that may be involved in a broader conspiracy. Even though they have a different tone, both have comedy and mystery elements.

Both have strong female lead medical protagonists with special skills that cause the hospitals to need them even though they're disliked for walking to the beat of their own drum.

Just different adaptations of the same famous wuxia novel by Jin Yong (Louis Cha); everyone has their personal favorite version(s). You can really choose any of them, but know this is the first part of the Condor Trilogy and is followed by The Return of the Condor Heroes; that latter is a different story. The third is Heaven Sword and Dragon Saber.
