I will note I originally comparing them to Marvel, and noting DH's consistency.
DC does have some good authors who produce great books (and I find even some of Geoff John's lacking. Post-reboot Hal is too much of a jerk, and not the fun kind of jerk like Guy, etc.), but only allows a few of them free reign.
And Dark Horse's output is, as I said, far more consistent. DC has no idea how to purposefully make a good book, they just luck into it.
Dark Horse's worst Star Wars book in the last decade is... well, I'm not sure, none stick in my mind as very bad. Maybe one of the star wars tales...? Or possibly a Boba Fett book I haven't read...? On the critically acclaimed side, Brian Wood is, as I've mentioned, a majorly critically acclaimed big name author who I'm surprised you give so little credit to. Heck, I don't even *like* him and I still admit that.
And note, for DH I'm using 'decade'. For the next two, I shall use 'two years.'
Marvel's worse stuff currently is, merely nothing to write home about, but I can't think of anything that's aggressively bad (extend to decade and it'd get Red Hulk, Ultimatum, OMD, etc., but thankfully those are in the past). And they have a long rack of critically acclaimed comics right now (some of which have very long runs as a bonus. There's more of Mark Waid's Daredevil than any two, maybe three of the ones you've listed!), so they don't lose out to DC there.
DC's worst stuff.... well, you've got books that have had three or four writers in 2 years, with a new direction with each writer, and in multiple cases at least one of those writers is Rob Liefeld. Their Static Shock was a bad joke (it turned out the editor and the artist worked together to cut out the original writer!), their Blue Beetle removed almost everything fun about it, pre-Lemire Green Arrow was weak sauce, Justice League Dark's first writer thought it was a good idea to waste the second issue breaking up a relationship that had no reason to exist in the reboot, Superman/WW seems mainly focused on showing how great Superman is and not portraying them very well as partners or having much in the way of romance, you get the idea.
Grab a random Marvel book and you run a risk of getting "eh," and a good chance of "this is really awesome!". DC book, you've got a chance of awesome, but you also run a chance of getting a real stinker. Dark Horse book, and while there's fewer "this is really awesome!", if you don't get "awesome," you get, "Hey, this is pretty good." That's consistency.
Likewise your complaints regarding Wonder Woman, while arguably fair, are in the grand scheme of things inconsequential and do little to detract from everything else that the series does right.
Oh, I've got more. The book is really much more of a Greek God, or "Wondy's Friends" book rather than a Wonder Woman book. While she's got a central role, she has very little development focused on her and a reader doesn't particularly know her all that much better now than we did 4 issues in.
Also somewhat on the sex issue front, but not just that, it has Wondy mysteriously putting up with the sexist Orion slapping her butt, abd includes bizarre moments like when he's being rude she decides to kiss him before punching him. Now obviously, that goes on the catalog side, but aside from that, leaves one wondering, "Why is she responding that way?", which is not something one should be wondering on the main character of a book.
Then there's the side issue that it's almost a separate continuity than WW in the other books. Relationship with Superman that has it's own title? What's that?
(And, speaking as a WW fan, it doesn't do much that hasn't been done before. Whenever people say they find the focus on mythology and monsters a 'new take,' I chuckle)
Even putting aside the gender issues, I simply think Wood's Star Wars is a superior book to WW that handles it's characters better, and ditto KotoR too, who's Zayne is a very compelling hero.
Compare the critical reception of Animal Man and Swamp Thing to Hellboy and BRPD over the past few years and tell me they're even remotely comparable in terms of quality.
Hellboy and BRPD are preeeetty high up in critical reception, actually... so yea, I'd take that comparison. Granted, some of the best stories tend to be earlier on, but there's some good HB/BRPD stuff recently too.
