The most important question is,
is TDK an action film? I don't think so. It's a drama with an action in it. It's more about exploring characters then anything else.
And those rating numbers are so vague. So opaque... but ok ...for the sake of over-simplified internet fanboy discussion...

t:
STORY/SCREENPLAY
The Dark Knight: 9/10
Mad Max: Fury Road: 7.5/10
Story-wise it's more like
The Dark Knight: 10/10
Mad Max: Fury Road: 3/10
SCORE
The Dark Knight: 10/10
Mad Max: Fury Road: 9/10
The Dark Knight: 10/10
Mad Max: Fury Road: 4/10
There's not many interesting parts in MM:FR OST, while TDK OST is pure awesome.
I'd have to watch both films again to be able to rate and compare the editing and all the technical stuff more precisely. But they are both top-notch quality in this regard from my non-expert perspective, since I'm not a director or an editor, so I can only report how I just feel about those things.
Overall, to me, TDK is 10/10, one of the best films ever, MM:FR is somewhere around 7-8/10, a great action film with an interesting somewhat minimalistic portrayal of characters (which I loved, there's not much talking yet you feel like you know the characters for a long time) but complexity-wise and story-wise it's lacking.
