She's better with Twelfth. I watched the clips on YouTube.

Also, this poll is the finale of Which is Better? Yes, took me 5 months to finish. New series coming soon.

I preferred her with Smith. She felt much more natural and warm.

Clara and Twelve reminded me of Sarah Jane and Four.

Depends on what you mean by better. Better chemistry and a better written relationship - Twelve. More likable as a character - Eleven.

@BenGMan730 So are you not doing Donna and 10 or Donna and 14? Whilst yes both doctors are played by the exact same actor (David Tennant), they are characterised differently compared to one other, which therefore makes them two distinctively different doctors / characters (It didn’t make sense to bring this up in the Rose poll as you don’t exactly see Rose with Meta-Crisis for a few episodes).

@Grandpa Lo70 No. I won't. I know Ten & Fourteen have different personality's, but the poll I'm doing is which companion is better with a different incarnation of the Doctor. I know Donna travelled with 2 of them, but she wasn't with him when he regenerated.
