This anime is not a masterpiece, it's not among the best. It's only recommended if you like anime or like these kinds of Isekai/LitRPG kind of stories.

Re:Zero and The Rising of the Shield Hero are both very good Isekai animes. The main characters of both shows are transported to another fantasy world where they quickly find out that it is not exactly the fantasy world of their dreams. They both try to do their best in a world that is set against them.

Both shows are about the same level of quality for an Isekai anime.

The premise of this anime sounds a little silly, but the anime turns out to be really good.

If you like anime and gaming, then this is a must-watch.

Both Re:Zero and No Game No Life are solid Isekai Animes of the same rank.

One major difference is that the main characters in No Game No Life are very successful in this new world they are transported to. They are kind of overpowered with their brilliant gaming skills.

No Game No Life is a solid suggestion if you want more Iskeai Animes after finishing Re:Zero.

People are thrown into a foreign land with nothing but hazy memories and the knowledge of their name. This group of strangers is given no other choice than to accept the only paying job in this game-like world, the role of a soldier in the Reserve Army. 

The Reserve Army has one goal, to eliminate anything that threatens the people in the world of Grimgar.

All the strong people join together and those remaining have to band together to survive in this world.

One such group of leftovers is lead by the charismatic priest Manato. The other members are the nervous thief Haruhiro, the cheerful hunter Yume, the shy mage Shihoru, the kind warrior Mogxo, the rowdy dark knight Ranta. Together they struggle to survive this harsh world.

Despite its game-like resemblance, this is no game. There are no respawns or do-overs. 

Grimgar is a kill or be killed world.

Grimgar: Ashes and Illusions is a good Isekai anime.

It's more Grim and Dark than most other anime in this genre.

It focuses more on the Mental and Emotional struggles of surviving in an RPG game-like world with no memories and having to kill goblins to survive.

Grimgar is more suited for an older audience than most other anime in this genre.

Grimgar is also an Isekai Anime where the characters are trapped in another world. This world is more game-like than Re:Zero.

Both shows are dark and brutal and the focus is less on action and plot and more on emotional and personal relationships between characters.

If you like Re:Zero then you will probably also like Grimgar. It is one of the better Isekai animes.

Akame ga Kill! is a dark and gory anime. If that's your thing then it's worth watching. But it's not the best of its kind.

It's not unique or among the best, but it's still worth a try.

Akame ga Kill! is not an Isekai, but it is a fantasy Anime and it has dark and violent elements. It is also made by the same studio as Re:Zero. 

The stories are not similar but they are both good. The characters are also not that similar, but they are interesting and go through incredible hardships.

Reborn: Apocalypse is in the LitRPG genre witch often has strong similarities to Isekai animes. Reborn: Apocalypse is kind of a transported to an alternative world type of Isekai story.
