Hmmmm...I'm not sure the examples always match up with the options, honestly. I wouldn't consider Inuyasha "Comic Anime", for instance, since I don't recall it making much use of the usual assortment of anime visual gags, like huge sweat drops, deformed expressions, ect.
Inuyasha is a show that goes from drama to screwball comedy at the drop of a hat, but pretty much plays it straight, visually. Teen Titans is a much better example of "Comic Anime" despite being American. If anything about the show stands out on the list, it's the big "Special attacks" the show uses, which would lend itself to a "High-Magic" D&D cartoon reasonably well.
In general, I'd vote for a simpler, stylized, "Anime-ish" art style for this theoritical D&D cartoon. Detailed characters tend to drag down animation, as other people have already mentioned. It would inflate the budget, at the very least. Anime style art also lends itself to characterization and expressing moods fairly well. It's much harder to do well with a more american, detailed style, which again can lead to a seeming stiffness.
And seriously people, "Anime-style art" is just that. It doesn't imply anything beyound that, so relax a bit, eh?
I'd be more concerned about frame-rate, story-telling, voice acting, choreography, ect.
(Huge Pet Peeve) Over-use of the ole' "Flying Side-Kick" Manuever. I swear this move is used about 69 times during the average Jackie Chan or Ninja Turtles episode. An easily countered move that relies on a running start should not be anyones preferred fighting technique...
Anyway, while I'm a sucker for Japanese Art (Although I only really follow a handful of shows) I like American stuff too. News and cartoons are pretty much the only T.V. I watch, actually.
Batman was a great show on a lot of levels. Again, the simpler, stylized art was a big factor in this, as was the freedom to pursue darker storylines. I wasn't actually a huge fan of the art style though.
Justice League looks pretty good, but I don't watch it much. (Not a DC fan)
Gargoyles was a great show for it's time. I wouldn't object to the style, although going back and watching the show, it doesn't seem as good as I remembered. (Animation in general hasn't aged very well, though)
The new Turtles show is very slick-looking, but the fighting choreography bugs me very, very often. Then again, most episodes have a near-brilliant bit of action, it just isn't consistant.
Not a huge fan of the Jackie Chan art, but generally have to give a thumbs up for the choreography, since it borrows from the man himself.
