The Fate/Stay Night Route With the Best Adaptation

gamerant.com:

Given its narrative structure in its original visual novel form, it's no wonder a pure adaptation of Fate/Stay Night is impossible. It's constructed with three different storylines, or routes, that must be played through in order. They're separate storylines, and yet they build upon each other as if they were part of the same narrative. They'll even make references to story beats and elements from the other two. The plot device of parallel universes isn't brought in until the third and final route, Heaven's Feel, but once that falls into place, the idea that these are all canon timelines existing simultaneously makes more sense, oddly enough. More so, when taken into consideration the fact that Fate/Zero, as a prequel, takes into account setting up all three of the Fate/Stay Night routes.

With that being the case, which route's adaptation did the best that it possibly could have in adapting it? Which anime adaptation of Fate/Stay Night did the best job of bringing the route it was adapting to life in animation, with a passionate narrative that best conveyed its story not just to fans of the visual novel, but also to anime-only watchers?

For a long time, the only anime adaptation that existed was the 2006 adaptation by studio Deen. Technically, it adapted the Fate route, which features Saber as the main heroine. However, the route itself was too bare-bones for a full series adaptation. Moreover, the creators appeared to have set forth on the premise that they could do like many other visual novel adaptations tend to do, and focus on one route but still pull the best parts from other routes and include them in the same adaptation, as a means to tie disparate storylines
