What is your favorite large canon and why?

Large Canons: Ad Astra Per Aspera, AIAD, Broken Masquerade, Dread & Circuses, End of Death, From 120's Archives, The Gulf, No Return, On Guard 43, Resurrection, S & C Plastics, Third Law, The Trashfire, Those Twisted Pines, What A Wonderful World

I would probably say 120's Archives/No Return (Vanguard Timeline) because I just like the idea of the Foundation and other GoIs sort of reforming and showing the anomalous to the world (not Broken Masquerade, that was the world stumbling into the Foundation accidentally).
