Cantina Shipments

What did you guys choose from Cantina Shipments?

I can't decide if i should go for Old Daka(Healer) or Boba Fett(Tank). Both are from Dark Side and required 80 Shards to activated.

Can someone tell me the advantage/disadvantage? is Old Daka the best healer? is Boba Fett the best tank in the game?
