Back in school I learned about the Saxon genitive, but I see it's rarely used in both written and spoken English. Is it true? Should I avoid to use it? It seems to me that it's more common when I'm talking about things belonging to someone.
Example 1: "This is Joe's car", not "This is the car of Joe"
Example 2: "This matches our company values", not "This matches the values of our company"
Is my interpretation correct? Is there any other nuance I'm not getting? Something like one being more formal or one being more commonly used in spoken language
