Under what merits has The Dark Knight been topped or hasn't yet by the MCU?

I disagree with the notion that Nolan's Batman couldn't exist alongside other DC characters. The true genius of the MCU is that they allow the solo characters to exist in their stories with their own respective tones and styles. If you showed someone The Winter Soldier they may tell you that version of Cap is too grounded to exist alongside Thanos and Thor, but obviously he can and does. I think the same could've applied to Bale's Batman...

Also, Batman Begins is a very comic book-y movie and could've been the perfect start to a DCU. And TDK and TDKR too, while certainly more grounded, have their share of comic bookiness as well. The DCU should've used Bale IMO.

Now... All those points being made... DANCE OFF! YOU AND ME, BRO! ROUND TWO!!!!!!!!!$&@
