Which Disney Parks Should we pick?

Me and My Sister and our friends are going to disney. If we had a choice of 2 parks what would you recommend? We like MGM for the 2rides ( tower & aerosmith ) & we like Magic because of all the Moutain rides ( Ex. Splash Moutain ) & We like Animal Kingdom because Everest & The Raft ride & We like Epcot because or Soarin & Test Track. What should we do ?
