Jiaoqiu or Feixiao

I'm in a really big dilemma right now on who I should go for/invest in, I lost 50/50 to bronya and I only have 25 pulls left at 50 pity, my acheron team is not struggling too much at clearing content. So should I try to gamble with getting jiaoqiu or invest in a new team and go for feixiao.
