There is appreciably little difference to choose from between, Pearl, Symphony, and Encore from a residential tower perspective, aesthetically speaking -- in terms of livability and mixed-use, I agree with @crisp -- Legends leads the way
^ I'd take that penthouse if I had to, I like roughing it from time to time.
I've always really liked the Pearl, such a nice departure from Edmonton's tired western skyline. It will be nice to see the Pearl "one-upped" eventually, but I won't be holding my breath in that regard. I do think CNIB (and Glenora Park) pair nicely with her.
The uptown skyline is now becoming an uptown skyline.
