Tony C,
You might be basically right about the big city negatives of Santiago - overdevelopment, noise, etc. Yes, it is also often boring.
On the other hand, it has positives that you don't mention:
Cheaper, nicer, and more honest taxi drivers than Santo Domingo;
Cheap, yet comfortable hotels for the budget traveler;
Less apparent street crime and fewer hustlers;
The ability to see virtually the entire core of the city by foot.
It's central location within an hour or so of interesting destinations in all directions is also nice.
Also, no place is as boring once one fits into its culture, makes friends, etc.
By the way, I can't tell the difference between the heat in Santo Domingo and Santiago. Santiago, though, at least offers escape in the nearby mountains.
