Advise: Staub Chistera/Nike Braiser or Staub Hexagon/Honeycomb Braiser?

Hi Guys!
I am looking to buy a 28cm Staub ECI Braiser, but I have realized that there are 2 version of Staub Braiser available for me to choose.

1) Staub Chistera/Nike Braiser
2) Staub Hexagon Structure/Honeycomb Braiser

So can someone tell me:
1) Why there are 2 different design?
2) Which is a better Braiser?
3) Are their cooking purpose and function different?

Looking forward to hear from fellow Chowhounders!
