Number 1 because it is the more powerful Pro model, I personally would still use the Air because I have always been satisfied with the Air variants from Apple.
Better for whom and for what?
Theoretically, the Pro is more powerful, but this increase in performance will be accessed by very few users.
The Air is more pleasant in daily use because it is a bit lighter and, thanks to the fanless design, absolutely noiseless. In addition, very few users are really satisfied with the Touch Bar, which is not available in the Air.
