I've actually never seen either of those!
Hmm okay
-Fullmetal Alchemist Brotherhood. It's amazing it's fantastic it's one of the best pieces of fiction in the fantasy genre. Just gonna copy paste the synopsis because I'll probably describe it weirdly:
"Brothers Edward and Alphonse Elric search for the Philsopher's Stone, hoping to restore their bodies, which were lost when they attempted to use their alchemy skills to resurrect their deceased mother. Edward, who lost only limbs, joins the State Military, which gives him the freedom to continue the search as he tries to restore his brother, whose soul is tethered to earth by a suit of armor. However, Edward and Alphonse are not the only ones seeking the powerful stone. And as they search, they learn of a plot to transmute the entire country for reasons they cannot comprehend."
(fma has 2 anime adaptations, Brotherhood and 2003. I've only seen brotherhood because you can't really stream 2003 anywhere. Brotherhood is also a much more faithful adaptation of the manga, so in general the writing is better--whereas 2003 had a completely different ending because the manga wasn't done yet when they made it)
-I also really like Frieren: Beyond Joureny's end. This one is more of a traditional fantasy, and is much slower in pacing, but the writing is fantastic.
"Taking place in a fantasy world, the story follows Frieren, an elven mage, as she embarks on a journey to reach the resting place of souls in order to reunite with her former comrade Himmel, whose Hero Party once slew the Demon King."
-Komi Can't Communicate is also really good, not a fantasy but a typical high-school slice of life thing. Generally the genre isn't my vibe but it's really well done and super funny.
"At a high school full of unique characters, Tadano helps his shy and unsociable classmate Komi reach her goal of making friends with 100 people."
I could keep going but I'm tired
