These kind of fanboys seem to be much rarer, and there's the matter of what is and isn't a poor decision varying from person to person.
Well, there's no accounting for taste. You can't really help it if you just don't like something.
As for me, other than some editorial problems at DC, both companies are doing well enough. Lots of good books from both publishers.
DC's got Action Comics, Batman, Aquaman, Batman/Superman, Astro City, Batman '66, Superman, Coffin Hill, Deadboy Detectives, Fables, Fairest, Swamp Thing, Justice League United, Justice League (Forever Evil really gave the series a shot in the arm), Grayson, Red Lanterns, Wonder Woman (though it'll drop in quality pretty soon), Sinestro, Multiversity, Superman Unchained (ending with the next issue), Sandman Overture (the best comic coming out right now from any publisher), Gotham Academy, and if the previews are anything to go by, Batgirl (coming out next week), then we've also got the upcoming Secret Six by Gail Simone.
Marvel's got Uncanny Avengers, Thor, The Death of Wolverine (the build-up sucked, but the actual mini has been good), New Avengers, Mighty Avengers, Bucky Barnes: The Winter Soldier, Captain America (new volume is launching, but it's got the same writer), Daredevil, Captain Marvel, Ms. Marvel, The Superior Foes of Spider-Man (ending next month), Hawkeye, All New Invaders, Black Widow, Elektra, Loki: Agent of Asgard, She-Hulk, Storm, then we've got a S.H.I.E.L.D series coming from Mark Waid, Tom Taylor's Iron Man, and the Angela series involving Kieron Gillen.
There are things I wish they would do differently (like getting a better editor for the Superman books, better treatment of the New Gods, getting Bendis away from the X-books, etc), but I can't fault either for a lack of good comics.
