I stopped enjoying Marvel/DC years ago. Way too convoluted, too many crossovers, personalities and power levels are insanely inconsistent, many writers are obnoxiously preachy about their beliefs/personal politics, characters come back from the dead more often than in One Piece etc.
Still, there were a lot of good runs - 52, Marvels, Ruins, Kingdom Come, Thor God of Thunder, Renew Your Vows, Simonson's, Oeming's and JMS's Thor runs to name a few....You really have to pick and choose though.
I've tried Archie. Newer stuff is all over the place. Older is just annoying because Archie is a giant butt-monkey and I usually dislike such protags.
European comics are superb. Asterix is absolute peak. Lucky Luke is really funny so far. I also really liked this one called Melusine, but unfortunately it went off the rails after Vol 20 or so when one author died (I think) and the other turned it from a dark comedy to some weird fantasy adventure for some reason.
Aside from that I also plan to read Mercy Sparx and Gold Digger at some point. There are also lots of one-shot comics I've liked.
