Check out kkow if you haven't yet... also shingetsutan tsukihime. Was good.

I saw your wish list! start reading Pandora Hearts. It is really good. Maybe difficult to read, but you can take it as a challenge.
Try again to read Trace. Is kind of slow, but it is still good.

Ganbare Seishuu! Ganbare Seishuu!

vagabond
chrno crusade
Gintama it is not just jokes when the story gets serious it is surprisingly good
black lagoon
addicted to curry

So something recent but still long? I don't know if it's any good but maybe Akame ga kill!

sorry everyone but I have already seen every manga suggested. My list hasnt been really updated

bloody monday
major
area no kishi
diamond no ace
beck
Bartender
kagetora
love hina
immortal regis
melo holic
if you don't mind light novels hakomari is really good

Yotsubato!
anything by Adachi Mitsuru
Ode to Kirihito
Taiyou no Ijiwaru
Planetes
A Girl by the Sea
Nausicaa of the Valley of Wind
A Distant Neighborhood

there are also many excellent action/mystery/adventure/historical series that are shojo, aka not your typical high school romance shojo (ex. Banana Fish, Himitsu, Angel Sanctuary, Ooku, etc. Certainly better than most seinen/shounen series of such genres I've read, not to mention more brutal, violent, and disturbing.)

My suggestion to you...

The best thing for you to do is look at other 's lists to see how much they compare to your's. Then, if they compare will, look at some of the series that you have not read, but keep in mind... what other's like you may not and what you like they may not. So, such as "good" are mostly meaningless.

Also, you would not be as pleased with a series that someone else has suggested, for you are already looking at them from a negative perspective. It might be best that you just take a step back from reading manga, for a few weeks, and see if your perspective changes.

Udon no Hito was just recently released and it's probably the best short work I've read in a while. You should try it if you haven't done so yet.

::Edit::
Heh, totally missed the "long manga" part. Anyway, I'd recommend Naoki Urasawa's Monster and 20th Century Boys. Definitely worth reading (assuming you haven't).

Ditto what Toto said. I usually just look at the lists of people who share the same interests as me (in general) and pick from there.

Well, currently I'm pretty much into Gangsta., but as Toto - more or less - has said it before: Tastes differ. ^^"

"It's like love is a bonus in your life. Even without it, I'm just fine. I don't feel like pointlessly searching for it. You don't have to make yourself unhappy." (Ookami Shoujo to Kuro Ouji)

"Why does it rain?" - "To create drama." (Drops (Andou Yuki))

Maybe try Living Game if you haven't already. It's an older style, but really quite enjoyable.

Kurozuka (anime also)
Red Eyes
Golden Boy (anime also)
GTO (i like the anime more)
Kara no Kyoukai: The Garden of Sinners (check out the movies in order movie nr 2, 4, 3, 1, 5, 6, 7. Amazing story)

Friedrich Nietzsche (1844 - 1900) - "Man is more ape than many of the apes."

Jean-Paul Sartre - "You are--your life, and nothing else."

Henrik Ibsen - "The majority is always wrong; the minority is rarely right."

thks for the udon manga rec. The ending was to sudden tho
