if it doesn't matter to you boy vs girl. Then I would go by which DOG melts your heart and wins you over. don't even take gender into the equation. Let the connection between you and the dog/puppy rule which one you get. You won't go wrong that way
Good luck and let us know and post pictures.
Also, when I was looking for my yorkie, I didn't take the first one I saw. A-L-L puppies are cute but be picky. You'll know when you've found the right one.
