Both story is about food and the main genre also slice of life. However, Tenno no Ryoriban is a drama based on the true story of a famous cook in Japan.

Both are medical related drama and tell the story about people. Though God's quiz is more of a crime mystery drama.

If you never watch C-drama because the eps are way too many, don't worry. Because Nirvana in Fire won't disappoint you. Personally, I hate long dramas. But this one makes me keep watching it without skipping any of the eps. Both dramas are very unique. It told about brotherhood and guy friendship a lot. The main attractions from both dramas are the strong bonds between the two best friends. Both dramas also have great actings and great cinematographic. You will be blown away by the beauty of each scene and the storytelling as well.
The Prison Playbook is more funny and shorter but it has also some dark cynical theme and storytelling. This drama is literally going to mess around with your emotions. One time you are laughing the next one you are either angry or crying. it's kind of bittersweet.
Nirvana in Fire is more serious but also makes you think a lot. The main protagonist here is very smart (Prison Playbook's protagonist is kind of dumb but also smart in a way). He is very cunning but that's what makes the drama is very interesting. He is cunning for a greater good and the way he is able to get ahead of his enemies is just mind-blowing. if you worry if the story is way too serious, it does have some comedy but the drama genre is more like a slice of life kind of thing than comedy. The story will touch you deeply and if you really really like the brotherhood theme kind of thing. You really need to check this one out. It also has a season 2 with a different protagonist but the background story is related. You can watch the season 2 without watching season 1 but I think I like season one better. But both are really really good.

Both dramas told a story about the youngest sibling which is always being taken advantage by the older siblings. Both are funny and entertaining as well as very unique. Be prepared for so many funny expressions from the main protagonist. You will laugh a lot.

Both dramas are about self-growth and family. The stories are very unique, memorable and entertaining. The differences are the main protagonist in Momikeshite is a guy and Kanna san is a woman. Momekeshite is way funnier and entertaining though while Kanna-san is a little bit more serious theme. Which is about a woman who was cheated by her husband, underestimated by people around her and try to focus on her dream.

Both are old mystery drama which was quite popular in Japan, so please forgive the low quality of the production. However, both are still quite enjoyable to watch in your free time and you will be really surprised by all the cast who played in it.

Both have a partner of a woman and a man who are solving cases.

Trick is harder to enjoy because it has way too many Japanese puns as a joke. The case is more interesting (its all mix of old legend and fake supernatural) and the characters are weirder.

Another difference is, the woman in Trick is the one who actually solves the case, but in Remote the one who solves the case is the guy.

Both are based on the tales of Journey to the West. The Journey to the west is closer to the original story and funnier. I also find the Sun Wo Kong here is more active like a monkey, funnier, smarter and real troublemaker than Hwayugi. If you really really like the tale Journey to the West and Sun Wo Kong, I really recommend you to watch this. Even though this drama is old, this is truly a masterpiece.

However, if you want more mellow and romance then choose Hwayugi.

I think both are good in different perspective.

Both dramas have a theme about romance with a robot.
Both also have ex-lover/crush as rival
Both are comedy romance drama

Both dramas have a theme about romance with a robot.
Both dramas have a heartwarming story, but Q10 has shorter eps and the robot is more genuine.
Both also show the growth of the male lead into a better person.
However, I'm not a robot is more like a fluffy cute romance whereas Q10 touch about strong friendship and bonds.

Both stories are about a body swap.
The main female lead, in the beginning, is interested in another guy.
I think Secret Garden is way more funny and interesting. It also has a more concise plot and clear ending. Its heartwarming with an unexpected plot twist.

Both dramas are based on an autobiography of a real-life figure in Japan.
Both are also set in Japan from the past era.
There is also a little bit of story about the effect of WW in Japan.

The difference between the two:
Tenno is about a guy who became the emperor cook, whereas Gegege is about the life of Gegege no Kitaro mangaka from his wife point of view.
Gegege has a longer eps (Asadora) whereas Tenno is short like a typical Japanese drama.

Both dramas have a topic about infidelity. Both dramas make you think about the meaning of marriage, family, and self-identity. Both dramas are the types that make you think and introspective. It's not necessarily entertaining but make you wonder. The story are realistic and can be relatable. The difference was in Dakara Koya, the female lead was cheated by her husband whereas in Anata no Koto wa Sore Hodo, the female lead is the one who was cheating.
