Depends whether from the story or the comfort or both or neither.

Story wise: Yi Yi. Couldn’t even describe the movie in words because it’s complicated in a beautiful way.

Comfort wise: Perfect Days. Hirayama taught me how to simply appreciate the beauty in what can be boring routines.

Both story and comfort: Interstellar and Project Hail Mary are currently competing for this spot.

Neither, a.k.a it’s a favorite for an entirely different reason: Obsession. No explanation needed, I guess.
