What is better to loose weight Jillian or Wii Zumba?

What is the better excersise for loosing belly fat...Jillian Michaels ripped in 30 where I burn around 120/150 calories or Zumba on the Wii which burns around 230? With Jillian you are using weights but burning less calories? I am smaller, 5'2, and 114pds.

Thanks!
