Being herders they may try to heard you. That is not uncommon in this breed from what I've read. Also some dominance issues is common. They are slow to mature physically and mentally. Again, I don't have any personal experience with this breed. It might be a good idea to talk to those that have owned them or that have evaluated them.

I think it is a great breed like many other breeds. Many breeds have the same qualities as this breed. But none IMO fits all of the categories that you mentioned. One thing I was looking for in this breed that I did see was that is was bred to be a companion dog. I didn't see this on any of the sites where I did some research.
