Balti versus European cookware
It's a cast iron pan, it will behave like any other cast iron pan.

Le Creuset probably makes it "better" in some way (ie. maybe thicker material...), but that should not make it better than traditional ones.

From the description (google translate form german page you linked): 
"Dishes from the Balti Dish are also called Karahi and are very similar to wok dishes" 

From what I see from videos, it is used as a deep frying pan (like a cross between a wok and a regular sautee pan).

So in most case, there are not difference or advantages to the Balti Bowl over other pans.
