I'd rather have Zagitova as Olympic champion than Medvedeva for thousand of reasons.
I would rather have Tsurskaya than Medvedeva or Zagitova as Olympic champion, but I can't say I would prefer Zagitova over Medvedeva. Medvedeva does deserves better PCS than Zagitova if they technical score matches. Medvedeva may need to move all her jumps to the second half of the program though, if she wants the technical score to match to Zagitova.
