As far as I know there is no better FF card anywhere in the world that gives you more value then the Aerogold.

$15k CDN gets you a free trip ($14k now). No card in the US will get you anywhere for less then $25kUS! That's more then double AP's requirment!
As well many of those cards have caps on them like $100k per year, many require advanced bookings etc.

As a FF program AP may not be the best, but if you collect mainly through CIBC (Diner's Club is not accepted enough to be worth it) I have yet to find a program with more value. It's no wonder that 60% of AP's rewards come from credit card usage as someone posted here a few days back.

If you run a business that uses CC a lot, it's the way to go.
