Yeah generally speaking Japanese anime is top dog. No one can really attempt to be as good as it. I don't watch a lot of anime anymore but I used to be heavily addicted to Inuyasha. After season 4 I think....I got a bit tired of it. But I get like that with all animes. They tend to go on too long and get really repetitive.
Has anyone see Samurai Champloo? I think there were only two seasons of it, but one of the best anime shows I've ever seen.
The same can be said about "Detective Conan".

Cartoon Network put it on at like three in the morning here so it got cancelled because no one watched it. Well, if they'd put the show on earlier then MAYBE it would have had a bigger fan following.
