Whether Avion is a better option than WestJet depends on how much you value flexibility in a rewards program as well as your preferred airline. Avion allows you to convert your points to different rewards: flights, statement credits, merchandise and more. Plus, you can apply them to any airline when booking a flight. However, if you fly exclusively with WestJet (and its partner airlines), the airline's loyalty program WestJet Reward, is the better option. Credit cards affiliated with WestJet Rewards also offer more travel perks than RBC's Avion credit cards.
