I realize there is a thin line sometimes between what is and isn't a superhero comic but I'm trying to delve into memories of some of the comics I liked as a kid though this is by no means a top 20 list.
Casper the Friendly Ghost
Wendy the Good Witch
Hot Stuff the Little Devil
Archie
Classics Illustrated
Various Tarzan stories and similar stories
All I can come up with right now discounting things that are kind of in the superhero category and even some of these kind of are.
Power with Girl is better.
Here is a new one for you

I definitely need to re-read it again soon.
I knew I'd forget a few, so I'll add:
Arrowsmith and the unfinished Battle Chasers. I never got into Battle Chasers when it was coming out, but the trade that I got was pretty awesome. Arrowsmith was a complete story and it was a cool take. Makes me want to re-visit a lot of those old Cliffhanger published comics, because they were done right, IMO. Creator-owned and passion projects of the creators.

Given that Tales established Susan Veraghen, it seems essential for the concluding novel Past Prime. Aside from that, while not all the stories are essential, they do add alot more flavor and depth to an already rich universe, whether it's a South American civil war or a Grendel versus a Vamp in a frozen wasteland, it really broadens the scope of Wagners opus.
Hellboy
Godzilla
Sabrina:CT
HIVE (Korean horror web comic)
Conan
TW Dead
AO Titan
Parasyte
anything Junji Ito produces
BELZEBUBS (black metal webcomic)
He has a costume and a codename and has squared off against Batman and The Shadow (both great crossovers), so while he's definitely a sociopathic villain not dissimilar from Hannibal Lectre, he feels ingrained in the world of superheroes to the extent I was reticent to count him, despite liking the character. His granddaughter Christine Spar, as Grendel, definitely fits the hero mold
The Kingsman comic
I don't think it'd be considered superhero, but I really liked Silent Dragon when I read it.
