Advantages to renting a residence as opposed to a rental property?

I was reading that if you occupy a rental property for more than 10% of the days it is rented in a given year, then the property is considered a "residence".  For example, if I rent out a property for 200 days in a year, and I stay there for more than 20 days in that same year... then the property is considered my "residence".

 

What are the tax advantages of renting a "residence" as opposed to a "rental property"?
