When the end credits roll

^ yes

The actual fight between Superman and Batman just pummeling eachother

Aquaman had some nice moments. Though that Africa cover is not something I'd count among that.

The war in the Snyder's cut... Ares, Zeus, some random Green Lantern, that small scene was better than the entire DCEU

The end credits.

The war at the end of Aquaman was satisfying to see in the Imax.

Also, in Shazam when the whole Shazamily appeared. That was the first time I heard the audience cheering during a DC movie.

My personal favorite part is the first flight scene in Man of Steel

Oh yeah, I have to agree with that one.

I agree with @Former Trooper

The flashback to the alliance of Amazons, Atlanteans, GL and Greek Gods fighting Steppenwolf (although very video gamey looking) was my favorite part
