Personally I feel that after Codex SM 2 years ago ish, they focused so much attention on most of the mariney-all-encompassing-fluff they forgot to actually make the codexes good. Wolves hit hard but have issues holding objectives and getting the most out of themselves at the same time.
And now BA have issues getting any decent models on the table, since if they fill up with Tac Squads they sometimes lose CT's, which is what makes them soooo good. And if they fill up with the hard hitting stuff (like the silly Blood-talons-Librarion-Douchebag-weeeeeeeIcanFLY-Dreadnought) they get almost NO models on the table. I've seen armies of literally a Character, 5 sanguinary guard, 5 death company or somethings, and the dread. Might even have been 4 guard. That all adds up to 1000 pts ish, possibly over... they seem to have 'nids-syndrome (in that ALL of their compulsory, supposedly hard hitting troops choices SUCK) AND Vanguard-with-Jump-Packs-syndrome (in that they cost FAR too many points to be worth taking over other units in one.
I know I exaggerate, but I honestly think behind all the book-cover decent stuff, BA and Wolves both SUCK, although BA slightly more so.
And as for the Marines being DoC-in-40K, I totally disagree. As a Marine Player I like the way they play and am comfortable with it (as if any player isn't, really...), but I disagree they are the uber army because their fundamental advantages leave so many weaknesses that they don't again cover. But I also disagree on the fact they can make Uber-death lists. I can't see people in 2k pts competing with Sicarius, 4 Tactical Squads, a full size Assault termy squad and some Land-raiders of some sort. Sure its beatable but its pretty godamn annoying to see the second hardest tank to destroy in the game (im not going into the three Monolith list...) a couple of times over, one of the hardest combat units in the game, the most versatile troops 4 times over AND a character making them all Ld10, re-roll Sieze the Initiative and have a USR (who ontop of that can instant death anything with a S6 Power-weap attack if he's willing to get close).
The thing with 40k and fantasy is that whereas in fantasy there are top tier armies who are competitive and can make uber-death lists, but in 40k although some armies have advantages over others, most armies have the capacity to build an Uber-death list, which is what makes it that little more balanced and/or unbalanced, practically depending on which way each individual game goes.
Seems complicated. But 40k and fantasy aren't comparable in the way that they have good and bad armies, because, well, they're all good in anything upwards of 2k points.
