Well I'm honestly not sure, but I know that right now JLA is kinda going through a rough time with members coming and going. Also If you didn't know, Wonder Woman and Superman are not in the book right now. JSA I think, at least in the beginning of the series was really good, but I have no idea what has been goin on lately. Sorry if I wasn't much help.
I like heroes better but i like how Green Arrow is doing right now or even Batman. They can injure people badly but they don't flat out just kill them like the punisher would. Though I do like Wolverine!
