We have an interesting movie face-off this year with an end to the Avengers as well as the end of the Star Wars sequel trilogy.
According to Wikipedia, Star Wars: The Force Awakens and Avengers: Infinity War are the third and fourth highest grossing movies of all time, respectively grossing $2,068,223,624 and $2,048,711,378, respectively.
I think Star Wars has more name recognition overall but Avengers has grown in popularity recently. Combined with the worse reception for The Last Jedi compared to Infinity War, I see Endgame beating Episode IX at the box office.
