i tend to follow "artists" more than comics, not cuz i'm a fanboi, but cuz they largely make it good or bad, you want good captn america? you need to read the marvel "ultimate" universe. Here's the skinny all marvel comics are in one universe (i forget the universe number, not that nerdy) so they make this alternative universe called the Ultimate universe, and title the comics like so..
Ultimate x-men
Ultimate spiderman
so on
The Ultimates is basically the avengers and if you've seen any marvel movie lately (ironman/captn america/thor) you'll be like why is nick fury black? cuz they wanted SLJ? no that's cuz they're taking their cues from the Ultimate universe.
try these

Mark Millar does them all? most of them? so maybe follow him,
i like the storylines of warren ellis also

no hero
supergod
i like these paperback all in one things i can't be bothered to get the comics as they come out monthly, heck i don't even have a comic store so these all in one's are great.
if you want more just ask i guess.
