7 Star Thrawn, Chopper or Sabine?

But if you have the option of either (as many will the second go around) - I still think Chopper makes the better choice - at least in theory. As I posted in the other thread, while I really like Sabine's pure damage output (and her crit synergy for the team), it seems as though Chopper's health recovery unique along with his ability to taunt, clear enemy buffs as well as his basic, which has a chance to reduce cooldowns, and buff an ally seem to me to be more favorable.

Again, this is me hypothesizing - and I would appreciate hearing any counter point, especially from those who have completed the 7* event either way.
