You can generalize the comics from any culture. Comics from the US tend to be more shallow, with less absolute continuity. They tend to either be superhero-focused, or the occasional slice-of-life (like Archie). There is less of a market for comics in the US, so you don't see a ton of variety. The art is more 'realistic', and it seems that US comic artists feel that it's a lot harder to draw in the US style.

Comics have a greater fanbase in Japan, so you're going to see a lot more variety there. There are a ton of genres in Japanese comics. They tend to follow a closed storyline and end with the main character having some sort of epiphany. The artwork is obviously different - more idealized. That's how art in Japan always has been.

The only other culture whose comics I'm familiar with is Korea. It seems that comics from Korea tend to be based on folktales or history. If-this-event-never-happened storylines seem to also be popular. The art here tends to have more details on people, but is similar to Japanese art. Again, this is how art in Korea has long been.

With anything that has several niches with noticeable differences, there will be rivalry. That can't be helped. It's rude, I think, for people to taut that one is better than the other. Obviously, both US and Japanese comics are good, because people buy them.

I do have a respect for US comics, they have very impressive detailed images now but at the same time the characters seem stiff on the picture and that just bugs me but in the japanese comics the characters seem to have more life in their movements and I really like that. Also In japanese comics stories of characters seem to actually have an end despite how long they can turn out to be. I like being able to say " I have all the Comic Party Manga" or " I have all the Cardcaptor Sakura manga." and not have to worry about some new story to follow.

Also, a Japanese mangaka will tend to express their character's emotions by drawing them, and a western artist will do it through the dialogue. You can read manga faster and it has a better flow because of this.

Where does that come from? "tend to be more shallow"...compared to what? Did you read Watchmen?

Don't confuse Archie with more serious titles. That's like saying saying Japanese comics aren't serious because of Doraemon and Crayon Shin-chan. You are mixing apples and oranges.
This is an incredibly boiled-down take.

I am a fan of both, i don't care whatever culture or country it comes from, if something is good, it derserves to be regconized
these battles of stupid
true artists are suppose to share each other visions and not battle each other
there are alot of ridiculous fans that are very prejudice and refuse to see the goodness of the other side because they are so stuck to one thing, reminds me of a lot of old people, i mainly see alot of anime/manga fans hate more on non japan related things instead of the other way around

The "rivalry" I see isn't usually propagated by what I would call "old people".

u misunderstood what i mean by old people, i was relating it to old people not wanting to accept new things
i was not talking about old people having rivarly issues

I got you now...

to me American comics lacks off genres.. since superhero is the main genre there...

Superhero might be the main genre, but there are all sorts of American comics. From indie to horror to mystery/noir to sci-fi...
