It probably depends upon where you are from. There's very little in any mall in the entire state of Florida that you can't find at a mall located in a medium-sized (or larger) city in the United States.
But, if you live in rural Montana or a foreign country, you might be keen to visit a mall when visiting Florida. But, I certainly wouldn't recommend driving all the way to Tampa for a mall. Nothing there would be significantly different than what you find in Orlando.
