Personally, I think its silly and waaayy too early to compare Salt Lake City to Phoenix.
According to the 2019 estimate as part of the
List of metropolitan statistical areas on Wikipedia:
Phoenix-Mesa-Chandler, AZ MSA is the
10th largest metro in the US with a population of
4,948,203
Salt Lake City, UT MSA is the
47th largest metro in the US with a population of
1,232,696
Phoenix as a metro has
4 TIMES as many people as Salt Lake does. Its population is larger than Boston, San Francisco, Seattle, San Diego, Denver, etc.
The fact that there is currently only a 19 tower difference between the two skylines based on this is shocking and shows just how much more suburban Phoenix is compared with Salt Lake (which is already very suburban).
Its also why I think Salt Lake punches ABOVE its weight in towers, especially for a western city.
