Which Amex Card should I be applying? Explorer or Qantas Ultimate?

What is the better deal for AMEX cards at the moment.
I predominately aim for Qantas points over the last few years, but wonder if i should start accumulating AMEX points.

Should i have the AMEX explorer care or the AMEX express ultimate?

This site cannot give individual financial advice about which card is better for you.

which program you choose depends on your own travel patterns and preferences.
