The only good beef brisket I've had came from TX, USA. And Seoul, South Korea.  The latter proudly stating it's inspirations are from Texas.

So I'd have to say BBQ even though every culture has their own.  They can have their own sure, it's just not as good as the stuff they have in TX.  Which is a stinker cuz texas sucks ass for every other reason.

I also think the quality of beef is superior in the US and Japan.
