The same idea can be brought to life in completely different ways.
Every author has their own experiences that affect their worldview and their storytelling, so even if two authors stumble upon the same idea, they will end up with the stories that would share nothing except for the premise. Sometimes these stories just emphasize different aspects of the main driving force of the plot, or just focus on different things, and show the points of view that are not explored by others. There are whole anime shows that share the same premise, but execute it so differently that in the end they don't even look similar at all.
These shows are both built on the political aspect of ruling a country, but the latter one is an isekai. The main difference is, though, that The Genius Prince focuses mostly on the characters, while Realist Hero first establishes the world building — at least in the anime. In the light novels that these works are adapted from, world building is the crucial aspect of both stories. But the main character in Genius Prince feels more creative in his ruling, while in Realist Hero he's just less stupid than everyone else.
These shows are about a student who enrolls in an academy specialized in honing special powers while being pretty weak and then ends up in a love-hate relationship with one of the most popular students, against whom he wins a magical duel by being smart. And yeah, both shows are also ecchi. The character development in Chivalry of the Failed Knight is better, and the main character even fails sometimes, especially when he starts overthinking.
Both of these shows follow an alien female lead who learns how to be human and, as a side-effect of found humanity, falls in love with an earthling. Also both of these shows have mechas that respond to the characters emotions and thoughts. And that's where Eureka Seven takes the lead: this show is better at building the relationship between characters in a more authentic way, while Darling in the Franxx suffers from showing characters being quite one-dimensional. That's probably the result of Eureka Seven being twice as long, though, and having more time to introduce the characters properly.
The similarity is that in both of these stories the curses and demons are born out of people's negative emotions, and the main character, a teenager, suddenly gets these powers and tries to use them for good. But that's the only thing that these shows have in common, aside from the fact that they both subvert the generic shounen clichés. The focus is absolutely different: while Jujutsu Kaisen mostly zooms in being a battle shounen and tries to fit as many fights and cliffhangers as possible, Chainsaw Man goes for a deeper and more dramatic character development route, at least in the second part, though it doesn't skimp on bloodbaths. Still, the nature of devils and curses is the same.
Both of these shows have a makeshift family of two spies caring for a cute girl. The main difference is that Spy x Family is an anime adaptation and thus already had a huge fan base, while Buddy Daddies is an anime original. The story in Buddy Daddies focuses more on the adult pair and on the family in general, while Spy x Family more often explores the characters individually. In Buddy Daddies the story feels more realistic than simply goofy, and portrays the child caring in a more believable way.
Technically, both of these shows follow the premise of a shadow figure brushing elbows with his main rival. Death Note was adapted from the manga, but Code Geass is the original anime series, and that allowed for better pacing and unpredictability. The problem with Death Note is that in order to fit all the plot of the manga into the anime, the writers had to omit quite a lot of events, so the second half of the show suffered a lot. Still, both of these series are ones of the most loved from the 00s.
Both started with remaking a Shakespeare play into an anime, but then suddenly added a huge mysterious fantasy side story that affected everything. And while it worked for the Blast of the Tempest, in the case of Romeo x Juliet it nearly destroyed the whole premise. Blast of the Tempest doesn't rely on magic to cover the plot holes: it relies on logic to avoid them. And it uses Shakespeare's The Tempest as a solid basis for the plot, whereas Romeo x Juliet just puts bits and pieces of the dialogue from the play here and there.
Welcome to the Demon School! Iruma-kun (Mairimashita! Iruma-kun) and My Hero Academia (Boku no Hero Academia)
Both of these shows follow a person who doesn't have any special powers entering a school for those who have these powers and then they mysteriously obtain them and now learn how to deal with them. The problem with My Hero Academia lies in a huge ensemble cast that doesn't get much development, while Iruma-kun focuses on its main cast and allows them to develop properly, portraying adults as dependable, and playing with the tropes in a more tactful way.
