ROTS Anakin and EOS Cade vs FOTJ Jaina and TUF Jacen

Revenge of the Sith Anakin Skywalker
Legacy: War Cade Skywalker

VS

Fate of the Jedi Jaina Solo
The Unifying Force Jacen Solo

All out. Which duo takes it?

The twins. Jacen is the trump card.

Anyone else?

Jaina would beat her cousin in a good fight, Anakin is probably more skilled than his grandson at this point but Jacen can hold him off long enough for Jaina to beat Cade.
