Which Science Champ Should I Upgrade?

Thing is duped (sig 40) and Human Torch is not. Who is best for end game content. Haven’t finished 6.2 yet or Variant 1 or 3. Thoughts as to whom would be most helpful at R5?

Haven't played either one properly, but my guess is on Torch. He can wreck mystics, whereas Thing is good, but I don't see him extremely useful in endgame

Human torch if you're looking for an attack team champ. Doesn't need the dupe to be effective
