If you have other Science champions who can semi-replicate what he does (CapIW to counter Unstoppable; Void/Spider2099 to counter regen, etc.) then it is debatable whether he is R3 worthy.
Unduped, he feels a bit too flimsy to me, and takes longer to get the best utility. I recently took him into Act 7, to counter Unstoppable/Evade, or Poison/Incinerate. In my (unskilled hands), Anti-Venom got KO'd pretty quickly, leaving CapIW and Rulk respectively to carry the load.
If you can dupe him, then the sustainability and quicker utility might push the needle.
