[@Prewiga] Well, ideally both, but...

Like Luffy, she wants to find One Piece, but she has a goal in doing so beyond becoming Pirate King. This is important to her, so she does look for people who she feels have the strength/skill to make the journey.

This doesn't necessarily mean they're superhuman monsters like her, but they would at least be very clever and wily like Ussop.
