Depends on what you want!

Audi is going to be a blast to drive-superior handling. Volvo is not famous for handling. What Volvo is good about is high quality materials, superior safety and value meaning cheaper than similar equiped luxury brands. As others mentioned, you don't want to drive other cars after you drive Audi. Similar is true to BMWs and Porsches. But Audi reliability is not going to be as good as Volvo. So if you value handling a lot, you will like Audi better. Otherwise, Volvo is a better value.
