The World of Apu is not on your list, but considering Pather Panchali and Aparajito are, I figured I'd chime in since you included the other two films of the Apu Trilogy, which I've written about. This is definitely the least of the three of The Apu Trilogy, if only because I found the pacing to be a little off, kind of strange. You spend so much time developing the Aparna and Pulu relationships that the solitary figure of the adult Apu needed a little further exploration. Ultimately, it caps off a trilogy of loss in the primary female figures in Apu's life, which understandably nearly drives him to the edge. I'd have fallen apart, especially with how rich these people are. The ending redeems much of this and makes it feel essential, even if it's not shot-by-shot, minute-by-minute as interesting and striking as Pather Panchali or Aparajito.
