I’m a DC Comics guy, but I still have to say that as it stands right now the MCU is better than the DCEU.
I do think the MCU peaked with Infinity War (Endgame obviously peaked financially but I believe IW is better and will stand the test of time) and the DCEU could improve if they continue to make fun movies like SHAZAM and Aquaman. But I can’t know the future.
Also, Wonder Woman was my favorite movie from that year.
