1062 easily.
1061 definitely had the most unique direction and did the most with the content, but I think 1062 was just the best put together of the three. Its easily the best animated and still elevated the content significantly.
Animation wise, 1066 is probably a bit better than 1061, but 1061 is just far better directed and follows through far more competently in connecting things scene to scene. 1066 had some amazing animation and great ideas in the storyboard, but I'm not sure all of them connected as well as they could have, with there being a lot of jarring cuts that killed the pacing of the action or shots that killed the scale or intensity of the scene.
1061 has a bit of a weaker first half as well like 1066, but unlike 1066, I 1061's first half still feels very well connected by interesting ideas, and we don't waste too much time on unrelated stuff(the Osome stuff was still connected to the main plot of the fight even if it dragged a bit) from the main conflict like what happened in 1066, where the Momo stuff was pretty much completely irrelevant to the rest of the episode.
All three are great episodes, but for me, its definitely 1062, 1061 and then 1066.
