Both of these films hold similar theming for the characters, both movies tell similar stories and have very emotional parts to them. Personally I think Grave of the Fireflies holds itself above Maquia in many ways as it relies less and less on plot convenience, lack of foreshadow and reason, aswell as being much more relatable and realistic.
