The scent of pine needles is unmistakeable. It's also environmentally friendly, and can be used for compost or fuel after christmas - or get a live one and replant it.
The only true advantages of having a real Christmas tree is that it is a real tree. It will provide the look and smell of a real tree which plastic trees and sprays cannot achieve. Otherwise they tend to add additional chores to the household such as cleaning up dropped needles and refilling the water tray.
Real trees are natural, smell great, are grown in the USA and Canada, are a renewable resource, and help tree farmers. They sequester carbon and filter air while growing.
