Paragliding or Hang Gliding?

Okay so I have the opportunity to do one or the other. I plan to move to the Caribbean in the next 3 years. I plan on sticking with whatever I do so I want to be able to do it in the Caribbean. I am going to Grenada so it is a mountainous terrain. Is one or the other better? Can you do one in the Caribbean and the other not? Any advice would help. I'm in the USA North-East right now so there are mountains here too. Thanks
