what is the best travel rewards credit card in canada?

I am told RBC Avion (sp?); however if you already have Aeroplan, then CIBC Gold Travel is good. They give you 25 000 points automatically for joining....that's a roundtrip from Toronto to LA.

I have an american express travel rewards card and i collect points really fast. I think it compares very well to others. And 100 bonus air miles helps alot.
