Yet another Zeta question

Clues in the title. I'm undecided on which to zeta next... Thrawn Ebb and flow or any of the three JTRs. I've read that JTR leadership is a force to be reckoned with but Thrawns is essential too. I don't have Thrawn yet but he's out later this month (4 days from now) and I can get him at 6*
