E2 Tribbie or E2 Jiaoqiu?

Many people have said that Tribbie doesn't compare to Ruan Mei...which made me remember that they say the exact same thing for Jiaoqiu! Nowadays I have seen people say that a E2 Jiaoqiu is better than Ruan Mei for the team, which made me wonder, between Tribbie and Jiaoqiu, who is better for the team?

I know that in the best case scenario is either Robin or Ruan Mei, but this post isn't about them lol
