Hrithik Barbara or Hrithik Aishwarya.The best chemistry???

I personally feel that Hrithik Roshan had the best chemistry with Barbara Mori and Aishwarya Rai in his career.which pair did you like more???

Hrithik Aishwarya, obviously ,without any doubt. 

Katrina and hritik for me had a sizzling chemistry with Aishwarya they were good and it's was nice to see two beautiful people togheter on screen but I don't find them sizzling at all
