With Ennis it pretty much depends on his mood, what series it is, and when in his career he happens to be writing the story. His relatively recently written JLA/Hitman story, for example, is a lot less scathing in its depictions of Batman than the actual Hitman story was, for example. He also did a pretty good version of Wonder Woman too, and admitted that like Superman she's a character that he can actually understand why they're the way they are.

Additionally, when he's writing a straight-up Batman story, he writes it like an actual Batman story rather than as a parody of one, if that makes sense? Basically if he likes what he's been hired to write, you can really tell it by how the story unfolds. If he's annoyed at something, he can either make the target of his scorn look ridiculous (like Wolverine did in Punisher Max), powertripping idiots (zombie survivalists in Crossed), or are horribly murdered (human traffickers in the Slavers).

As for the Real Men trope that appeared in his earlier works... yeah, that's something that he realised himself wasn't that great a stock character either, and has gone on to deconstruct it in works like the Boys, for example. His later works
