Storywise, Iron Man’s series is probably the best of the lot. Whilce Portacio’s reboot of the armor is pretty cool. It’s rushed–because they had a year to tell the story they wanted to tell, but if you just read it as a standalone reimagining of Iron Man, you can have some fun with it. Not a lot. But some. There’s a Thing/Hulk fight.
But no, none of it matters.
