When Comparing to of DC films Nolan fits but if you're going for actual influence than for Joker it's Martin Scorsese he was once attached and the film was heavily influenced by Taxi Driver and King of Comedy where Snyder is more in the range of Michael Bay with better visuals.
Money isn't arbitrary it, awards, and critic response are the only objective way to measure films everything else is subjective.
MoS and BvS made money but not close to what WB wanted them too.
The MCU also made a Billion with their 7th film Iron Man 3 what did the DCEU's 7th film Shazam make? & and I like Shazam it's my favorite DCEu film but trying to equate the early MCU to the DCEU is an false narrative. The MCU weren't making record breakers and had problems behind the scenes with Phase 1 but nothing close to the DCEU's issues most of which were created by WB Executives meddling.
There are very few comic book films that can be considered "Auteur" projects especially ones connected to larger cinematic universe or made to be franchises. They are IP's owned by major corporations meant to create films that will make tons of money and spring board into franchises. They can be entertaining and have thought provoking messages but they are no where near "Auteur" Projects except to try to some how to make them sound classier.
