Disney is fun, but for most teens, there are not enough thrill rides to make it worth the cost of the ticket, IMHO. MK has Space Mountain and Splash Mountain, Epcot has Test Track and Mission Space, DHS has RRC and TOT, and AK has Expedition Everest and Kalu River Rapids. Universal has parks full of thrill rides.
That would certainly not be the case with my older kids--especially if they had never been to WDW or at least not been in a long time. As far as ticket costs go--Disney hits you hard on costs the first three days--after that it is very, very inexpensive (ticket-wise) to stay up to ten days. They would be out just as much to buy two days at WDW and then tickets to Universal. Might as well just do the ten day tickets at DIsney. OP will have to decide if would be worth it to split up (I would hate that--1/2 of us at WDW and the other 1/2 at USF).
