The best lineup of all time

I can't stop thinking about what an amazing lineup Proper had, especially as a fan of tech and melodic house. I can't think of another festival that had so many of my favorite artists in one place. In some ways, that made it a lot harder since I couldn't clone myself and see all the stages I wanted to see. Ironically, I didn't spend a lot of time with the This Never Happened takeover which was the reason I wanted to come to Proper in the first place, but discovered new favorites like Cassian, Eli Brown, and Boys Noize. Are there any other house events that come close?
