Best Single Episode?

I’m rewatching the series and have finished Season Six. I’d have to say its season finale is best. From the murder of Pycelle and the destruction of the Sept with everyone in it to the suicide of Tommen - and Cersi’s decision to scatter his ashes atop its devastation, the death of Walter Frey at the hands of Arya, the appearance of Varys in Dorne to meet with Lady Olenna, the confrontation between Davos and Melisandre, the appeal of young Lady Mormont to have the northern houses support Jon, and the massive fleet carrying Danys Stormborn toward Westeros. Whew! Did I miss anything?
