Calgary has a lot more tall buildings.

Edmonton has a cool downtown LRT subway.
Of course having the tallest skyscrapers & the longest subway stations in Western_Canada doesn't matter to a lot of people.
If you are from Calgary & visit Vancouver, you will be surprised as to how small most of the buildings are in Vancouver. If you are visiting from Edmonton, you will be surprised to see how much shorter the underground SkyTrain stations are when compared to the downtown LRT subway in Edmonton.
If you are from Edmonton, you will be surprised to see how small backwater Victoria, BC is, despite it being in a mild winter climate. Edmonton isn't just a mighty provincial Capital, it's almost on the same urban scale as Perth, WA. That's despite Edmonton being in a very cold winter climate zone.
Fortunately, BC was never able to gobble up Alberta, or strongly influence it. BC stopped a huge destination mall from being built in the 1980s. However, BC wasn't able to stop the West_Edmonton_Mall from being built.
