Once upon a time, two brothers passed the happy days of their childhood by studying alchemy, which is governed by the equal transfer principle: an eye for an eye -- you can't get more than you give. But these brothers tried to defy that law, and a horrific accident resulted. Now, the older brother, Edward, is called the Full Metal Alchemist because of his metal limbs, and the younger, Alphonse, is a soul without a body, trapped within the confines of an automaton. Together they search for the power to restore themselves, to find the lives they lost so long ago...
Yusuke Urameshi was a normal middle school punk until he was hit and killed by a car, while saving a child. His selfless action earned him the right to gain his life back and serve as a detective of the spirit world, keeping the world of the living safe from a myriad of demons. But being reborn has its price: Yusuke must hatch a spirit beast that will develop according to his actions, and if he doesn't act in a good and honest manner, it will eat his soul. Can Yusuke protect the human and spirit worlds and still manage to save himself in the process?
YYH and FMA both have great action and stories, and kickass characters. If you liked one, try out the other.
Not that i'm an absolute meter, but I have rather specific tastes in anime and manga, and these two make it into my "favorite of all time" category; something I don't take lightly.
More objectively, they both center around a teenaged boy with a lot of room to grow. They have similar personalities and a tight network of supporting characters and friends. These characters are both endearing and badass at just the right moments leaving you wanting more. While Yu Yu Hakusho is more on the fighting end of things, the later half has the deeper, character building and challenging plot developement that sucked me into me me to FMA. Both are of a good shounen tradition that continues strong over the years.
Over a century ago, mankind was devoured by giant beings of unknown intelligence and origin known as Titans – creatures that eat humans alive indiscriminately and for no apparent reason. The remaining population has managed to survive the last hundred years only by building a multi-walled city capable of keeping the Titans at bay, training military recruits to patrol the perimeter and gather intelligence about their mysterious foe. Eren and Mikasa have lived a relatively peaceful life behind the city's walls, but when a massive Titan appears, smashing the outer barrier and unleashing a wave of terror, their lives are brutally changed forever...
Both of these series feature an angry young soldier motivated by the death of his mother and dealing with the horrors of war. Both series are also set in a European-ish setting that feels historical but doesn't quite fit into real-world history, with strange-but-cool technology. Also, both series feature a mysterious father figure with a secret that might solve some of the series mysteries.
It's not a completely perfect rec--FMA has plenty of comedy in it, while Attack on Titan takes itself VEEEERY seriously (for the most part), but I definitely think they have a similar appeal.
In the French countryside, a large white dog roams from place to place, helping townspeople where she goes; but the ungrateful people think she is a menace and a threat, and seek to capture and kill her. Meanwhile, in a town near the Pyrenees Mountains that separate France from Spain, a young boy named Sebastian lives a life of loneliness. Left behind by his gypsy mother when he was just a baby, Sebastian has been raised since birth by an old man and a young woman; but even though he is surrounded by a loving family, Sebastian is picked on by the other children and longs to know his real parents. When the white dog arrives in Sebastian’s town, her and the boy happen upon each other and become fast friends. Sebastian names his newfound companion Belle and does his best to keep her safe, but ultimately the two must flee their home. With mountains and adventures ahead of them, Sebastian and Belle set forth to escape danger and find Sebastian’s mother.
While it's much more action-packed, darker, and more violent than Meiken Jolie, Full Metal Alchemist is also about a boy's journey motivated by the absence of his mother. Both series have their moments of adventure and stillness, and both focus on the friendship between the main character and his travelling companion, as well as the places and people he encounters.
Yori Yuki has loved his twin sister ever since he can remember. While his parents brushed it off as a child’s fantasy, he always knew it was true love; but because it is incest, taboo, a forbidden love, he did his best to eliminate those feelings. 15 years have gone by and his feelings never wavered; in fact, they have grown stronger. He’s watched his sister Iku grow up and become a beautiful woman, and now, he can no longer contain his feelings – Yori confesses. Yet even if Iku reciprocates his feelings, that doesn’t change the fact that they’re brother and sister. Can forbidden love last?
These stories don't have much in common at the first sight, but if you look closely, you'll see it. Both series are primarily focused on the strong bond between siblings. And also in both series the siblings committed taboo. You can see complicated but different relationships and specific problems main characters try to solve. Both stories are deeply touching and make you think of something you perhaps have never thought of.

She is a Synesthetist – a person able to use all five senses at once – who harbors a burning desire for revenge and has a past shrouded in mystery.

Danger lies at every turn for Canaan and ultimately the rest of mankind…
I am recommending these animes to each other for the simple fact that they have a similar feel. also there seem to be big conspiracies going on. not to mention innocent children with awesome skill being used by the miliator and or terrorist organization
