Kotonoha no Niwa, Fate/stay night: Unlimited Blade Works 2nd Season Recommendations
If you look at the animation as an art, I think you will enjoy as much as Garden of Words Unlimited Blade Works. Indeed, the two animes have great animation and impressive backgrounds.
Moreover both animes have a romantic relationship with the protagonists who fail to declare the beginning. (Rin / Shirou, Yukari / Takao)
Contrary to Garden of Words is a slice of life, Unlimited Blade Works is an anime with action, fighting and supernatural / fantasy environment.
Finally, look at the two at least to understand what is capable Japanese animation today.
