Spy x Family is really good, but I'll wait until ep 4 or so before I decide if it is better than Kaguya-sama which is killing it so far. I haven't seen Summertime Render yet, but the dance one just didn't do anything for me. Aharen is okay, but more just silly.
Ones not in the poll which I think are better than Dance/Aharen-san (can't say about Summertime):
Ascendance of a Bookworm S3
The Executioner and Her Way of Life
Deaimon: Recipe For Happiness
In the Heart of Kunoichi Tsubaki
