Best credit cards at RBC?

Wife and I both have pretty basic credit cards (shamefully I've had the same cash back card for 15 years) and keep getting bonus offers from RBC for Avion or Westjet cards.

We each have just one card, pay for everything on card then pay off at eom. Good credit as far as I can tell.

Curious if anyone has experience with either bonus points system, and how they found utilizing said points.

Thanks a million to any comments.
