#1 Chris Jericho vs. 'Hangman' Adam Page

This match has been confirmed by AEW to be taking place 'in the future', but given what a beautiful World Championship belt they unveiled at Double or Nothing, this is one we want to see now. If AEW can build it properly, this will have the big fight feel that Kenny Omega vs. Chris Jericho did, as it clearly pits the future of All Elite Wrestling up against a wrestling icon.
This isn't a match that people would have expected to crown the first AEW Champion, but given how great Jericho has been over the past few years and the potential that Hangman has, it's going to be great.
Hopefully this one isn't saved for All Out in August, as that's too long to wait, but AEW need to find time to give this the build it deserves, as it will set the stage for it's main event picture for years to come.
