"The best" meaning what? The one we like the most? The one we think would win the most battles? The one with a more developed character arc? Something else?... If it's which one we like the most, I'd suggest having the question say "favorite" in it. Otherwise, I'd like clarification on "best".
It's also interesting that you didn't have an "opt-out" option like "All of them" or "I can't decide", because honestly I'm kind of leaning that direction, lol.
