I liked
The Losers a great deal. The Losers are sort of supporting characters in their own comic - most issues are psychological profiles of other characters (often enough nazis), who tend to meet a gruesome fate at the end of the issue, falling prey to their own character flaws; Neil Gaiman talks a bit about this in his introduction to the collected run. Also: grotesque faces, big explosions, absolutley apocalyptic devastation.
I've been reading
The Demon - Kirby made the original premise up in a very short time, and it feels like the stories kept that spontaneous vibe up - there's a lot in there that doesn't make sense (even by Kirby standards), the ESP stuff is kinda wtf, and there's some blatant cribbing from classic monsters (werewolves,
Frankenstein) without using the actual creatures, which feels weird as well. But it's still good fun.
I've got the first Kamandi hardcover but haven't read it yet. Still, I had to be a fan as soon as I saw this:
