I love those little Karachi's from Pakistan, but they are a bitch to break open. I wouldn't use Niles(Egypt) because I'm afraid of so many fakes of them. I have yet to hear of a fake Karachi. Well take that back.There are some, but you can plainly tell because the BN number and expire date isn't in the dot matrix. Its in blue ink and looks like a 1st grader stamped it on. As for Turkey I haven't used them, but if get them from a reliable source I'm sure its just as good as the rest. They are all the same in my book as long as they are legit.
